The correct question is
<span>Find the area of sector GHJ, given that theta = pi/4 radians. Express your answer in terms of pi and rounded to the nearest tenth (given that GH is a radius of 5 cm)
</span>
we know that
[area of a circle]=pi*r²
for r=5 cm
[area of a circle]=pi*5²----> 25*pi cm²

if 2*pi radians (full circle) has an area of ------------> 25*pi cm²
 pi/4 radians---------------------------> x
x=(pi/4)*25*pi/(2*pi)------> x=3.125*pi cm²
<span>rounded to the nearest tenth------> x=3.1*pi cm</span>²

the answer is
3.1*pi cm²

You hike 190 meters up a steep hill that has a 33∘ angle of elevation as shown in the diagram.
erik [133]

Answer:

b = 159 m

a = 103 m

angle B is 57 degrees

Step-by-step explanation:

Let’s start with getting the measure of angle B

Mathematically, since we have a right triangle , we have to subtract the given angle from 90 to get the other acute angle

So we have the measure of B as;

90-33 = 57 degrees

To get the value of a, we use the appropriate trigonometric ratio

a faces the angle 33, that makes it an opposite to that angle

190 faces the right angle and that makes it the hypotenuse

Mathematically , the relationship between the two is that trigonometrically, they are related by the sine which is the ratio of the opposite to the hypotenuse

so, we have it that;

sine 33 = a/190

a = 190 * sine 33

a = 103 m

to get b, it is adjacent to the given angle

So with the hypotenuse, the ratio between it and the hypotenuse is the cosine

so;

cos 33 = b/190

b = 190 * cos 33

b = 159 m
