Answer:
92
Step-by-step explanation:
Answer:
x=9y=45°
Step-by-step explanation:
x=9y (being the base angle of triangle)
or, x+90+9y=180 (sum of angles of triangle)
or, x+90+x=180
or, 2x=180-90
or, x=90/2
x=45°
so, x=9y=45°
7(2x + 3) + 2(2x + 4)
Distribute/multiply 7 into (2x + 3), and distribute 2 into (2x + 4)
(2x(7) + 3(7)) + (2x(2) + 4(2))
14x + 21 + 4x + 8 Combine like terms
18x + 29
