@esamalaa

Answer 1

tan(theta)=x/15

Answer 2

A. cos 10° = x/12
B. tan 10° = x/12
C. tan 10° = 12/x
D. sin 10° = x/12

Answer 3

sin theta =x/12

Answer 4

Find the value of x to the nearest whole number. You're gonna needa explain this to me later haha x)
A. 21
B. 28
C. 26
D. 58

Answer 5

sin37=x/35
calculate x

Answer 6

Do I multiply & then divide those?

Answer 7

first find value of sin37 by calculator
then multiply this value by 35

Answer 8

I'm at home, I don't have a calculator..I can try to find one omg !!!

Answer 9

21 is the answer

Answer 10

okay, so for those how did you find the value of 37?

Answer 11

& 4 more, sorry about this :( Find the value of y to the nearest whole number.
A. 21
B. 28
C. 26
D. 58
same picture

Answer 12

37 degrees is the angle

Answer 13

cos37=y/35
y=28

Answer 14

okay awesome, i get you.
Find the value of x to the nearest whole number.
A. 12
B. 15
C. 16
D. 24

Answer 15

tan40=x/19
so x=16
cos40=19/y
so y=24

Answer 16

Using the figure below, find the measure of ∠A. Round your answer to the nearest degree.
A. 29°
B. 30°
C. 33°
D. 57°

Answer 17

After this, it's just 1 more that I need

Answer 18

sinA=22/40=.55
then
A=sin^-1(.55)=33 degrees

Answer 19

Using rectangle ABCD, find the value of y to the nearest tenth.
A. 15.8
B. 25.4
C. 25.6
D. 32.5

Answer 20

cos38=20/y so
y=25.4

Answer 21

Got it, thank you so much :) message me!

Answer 22

anytime :)
