Answer:
D
Step-by-step explanation:
It is a right angled triangle so you can use the SOH-CAH-TOA rules of trigonometry:
We have the hypotenuse and need to find the length adjacent to the angle so use CAH
cos 70 = x / 12
x = 12cos70 = 4.104...
A) 4.3
hope this helps!!!
r = 13
these angles are vertical and are congruent
8r + 6 = 9r - 7
6 = r - 7
13 = r
3.1(p - 2.7) simplified:= 3.1p-8.37
use mathaway! it helps a lot
-6.5
-2(p - 1) = 15
-2p + 2 = 15
-2p = 13
p = -6.5
