The measure of the angle 2 is 133° and the measure of the angle 3 is 47°.

<h3>Classification Angles</h3>

They are a lot of classifications for angles like: complementary angles, supplementary angles, right angles, and others. See below:

complementary angles - two angles whose the sum is equal to 90°.
supplementary angles - two angles whose the sum is equal to 180°.
right angles - angles whose the measure is 90°.

From the figure, it is possible to see that:

- the angles 1 and 3 are supplementary angles

- the angles 2 and 3 are supplementary angles

Therefore, if angle1 is 133°, you have:

angle_1 + angle_3 = 180

133 + angle_3 = 180

angle_3=180-133

angle_3=47°

If angle3 is 47°, you have:

angle_3 + angle_2 = 180

47+ angle_2 = 180

angle_2=180-47

angle_2=133°

What the answer now

stiks02 [169]

Answer:

35.6 yd²

Step-by-step explanation:

Area of ∆UVW can be solved if we know the lengths of 2 sides and their included angle.

We are Given just 1 side, UV (w). Use the law of sines to find UW (v).

Thus:

$\frac{v}{sin(V)} = \frac{w}{sin(W)}$

W = 137°

w = 19 yd

V = 180 - (137 + 22) = 21° => sum of triangle

v = ??

Plug in the values and solve for v

$\frac{v}{sin(21)} = \frac{19}{sin(137)}$

Multiply both sides by sin(21)

$\frac{v}{sin(21)}*sin(21) = \frac{19}{sin(137)}*sin(21)$

$v = \frac{19*sin(21)}{sin(137)}$

$v = 10 yd$ (approximated)

Find area of ∆UVW:

Area = ½*UV*UW*sin(U)

Area = ½*v*w*sin(U)

= ½*10*19*sin(22)

Area = 35.6 yd² (to nearest tenth)

Which of the following equations is equivalent to S=pi r^2 h

lara31 [8.8K]

The equation that is equivalent to S=pi r^2 h is h = S/pir^2

<h3>Subject of formula</h3>

This is a way of representing a variable with another. Given the equation

S=pi r^2 h

We are to make 'h" the subject of the formula.

Divide both sides by pir^2

S/pir^2 =pi r^2 h/pir^2

h = S/pir^2

Hence the equation that is equivalent to S=pi r^2 h is h = S/pir^2
