Answer:
y=3 x=-20
Step-by-step explanation:
2(3y-5)+12y=-4
6y-10+12y
18y-10=-4
18y=6
y=3
2x+12(3)=-4
2x+36=-4
2x=-40
x=-20
Answer:
Option 2:
tangent squared (theta) + 1 = secant squared (theta)
Step-by-step explanation:
1 + tan²X
1 + sin²X/cos²X
(cos²X + sin²X)/cos²X
1/cos²X
sec²X
Answer:
Step-by-step explanation:
2x + 3 + 4x + 2 + 2x - 1 = 180 (bc the sum of the angles of a triangle = 180)
8x = 176
x = 22
2x + 3 = 47
4x + 2 = 90
2x - 1 = 43
