1. 3/3 2. 3/4 the answer is 3/4
Answer:
Step-by-step explanation:
Sum of all angles of triangle = 180°
15x + 3 + 3x - 1 + 52 = 180
15x + 3x + 3 - 1 + 52= 180
Combine like terms.
18x + 54 = 180
To find the vlaue of x, we have to islolate x
<u>Step1:</u> Subtract 54 from both sides
18x = 180 - 54
18x = 126
<u>Step2:</u> Divide both sides by 18
x = 126/18
x = 7

Step-by-step explanation:
Answer:
Use trig
Step-by-step explanation:
sin(55) = x/21
x = 21sin(55)
use calculator in degree mode
cos(55) = y/21
21cos(55) = y
