Answer:
x=6
Step-by-step explanation:
Combine like terms:
6 - 8x = -2x - 30
add -2x to both sides:
6 - 8x +2x = -30
Combine like terns:
6 - 6x = -30
subtract 6 from both sides:
-6x = -30 - 6
Combine like terms:
-6x = -36
Divide by -6 on both sides:
x=6
Answer:
1/2
Step-by-step explanation:
According to pythagoras theorem;
(sinx)²+(cosx)² = 1
Given that sinФ = √3/2
Substitute into the formula
(√3/2)²+(cosx)² = 1
3/4+(cosx)² = 1
(cosx)² = 1 - 3/4
(cosx)² = 1/4
cos x = √1/4
cos x = 1/2
Hence the value of cosФ is 1/2
Answer:
1. 3x +7x = 360°
10x = 360
x= 36
measure of first angle = 36*3= 108°
measure of second angle = 36*7 = 252°
