The approximate angle of elevation if Brendan looks up at the tower is 20.03°

The angle of elevation if Brendan looks up is as follows;

using trigonometric ratios,

sin x° = opposite / hypotenuse

sin x° = 50 / 146

sin x° = 0.34246575342

x = sin⁻¹ 0.34246575342

x = 20.0271724581

x = 20.03°

Therefore, the approximate angle of elevation if Brendan looks up at the tower is 20.03°

Answer:

20%

Step-by-step explanation:

An easy and simple way to solve this problem would be to divide 60 by 300, keep going threw the decimals until you have no remainder, which gives you .2,

60/300 = .2

then you multiply .2 x 100 for your % answer, you could also count by 60s until you reach 300,

60 x 5 = 300

100/5 = 20%

hope this helps a lil!

Answer:

70 is what percent of 280?

Step-by-step explanation:

Percent means per 100. So the example question asks 70 out of 280 is what percent. You can do this problem a couple of different ways.

1. Set up a proportion (two fractions equal to each other,) and solve.

70/280 = x/100

reduce the left side.

7/28 = x/100

reduce further.

1/4 = x/100

cross-multiply.

1(100) = 4x

100 = 4x

divide by 4

100/4 = 4x/4

25 = x

70 is 25% of 280.

OR

you could divide directly and move the decimal two places to the right to find the percent.

70/280

= .25

move the decimal two places to the right.

.25 becomes 25%

I can edit if you actually wanted to see 60 and 300. Hope this helps!

Considering the properties of a rhombus, ΔDGH ≅ ΔEFH by the SAS theorem.

When two sides and an included angle in one triangle is congruent to two corresponding sides and a corresponding included angle of another triangle, the SAS congruence theorem states that both triangles are congruent to each other.

Given that DEFG is a rhombus and its diagonals bisect at H, using the properties of a rhombus, we can deduce that:

This means that triangle DGH and triangle EFH meet the SAS congruence theorem criteria to prove that both triangles are congruent to each other.

Therefore, based on the SAS congruence theorem, triangle DGH is congruent to triangle EFH.

Answer:

y = 35 degrees; x = 10 degrees; z = 135 degrees

Step-by-step explanation:

We can find the measure of y using 180 - (85 + 60) = 35

We can find the measure of x using 180 - (105 + 65) = 10

We can find the measure of z using 180 - (35 + 10) = 135

Answer:

Step-by-step explanation:

37-17.3=19.7 which would be the value of x

Answer:

1) x/2 + 1
2) x/2 + 1
3) x/2 + 1

Step-by-step explanation:

1) (2x * 1/4) = (2 * 1/4 * x) = (1/2 * x) = (x/2)
(4 * 1/4) = (4/4) = (1)
(x/2) + (1) = (x/2 + 1)

2) (1/6 * 3 * x) = (3/6 * x) = (1/2 * x) = (x/2)
(1/6 * 6) = (6/6) = (1)

(x/2) + (1) = (x/2 + 1)

3) (1/4 * x) = (3/12 * x) = (3x/12)
(3x/12) + (3x/12) = (6x/12) = (1/2 * x) = (x/2)
(9 - 8) = 1
(x/2) + (1) = (x/2 + 1)

The expanded form of the expressions is 2x + 1 and x/2 + 1

Given the expression 1/4(2x + 4)

Expand the expression

1/4(2x + 4) = 1/4(2x) + 1/4(4)

1/4(2x + 4) = 2x + 1

For the expression 1/6(3x + 6)

1/6(3x + 6) = 1/6(3x) + 1/6(6)

1/6(3x + 6) = x/2 + 1

For the expression 1/4 x + 9 + 3/12 x - 8

Simplify the expression

1/4 x + 1/4x + 9 - 8

2/4 x  + 1

1/2 x + 1

The ratio of the number of tulips to roses in Julia's garden is 5:4.

A ratio is a quantitative comparison between two or more quantities or values.

Let the number of roses Julia planted is denoted by 'R',

and the number of tulips she planted is denoted by 'T'.

According to the given information,

"One half of the number of roses Julia planted is 2/5 the number of tulips she planted."

So, the mathematical expression is

(1/2)R = (2/5)T

T = (5/2)(1/2)R

T = (5/4)R

As, the ratio of the number of tulips to roses is T:R, which can be expressed as (5/4):1 or simply 5:4.

Therefore, the ratio is 5:4.
