(x+1)-(-2x-5)
=x+1+2x+5
=3x+6
=3(x+2)
Answer:
X = 30
Step-by-step explanation:
Because every triangle adds to the total of 180
so 102+48=150 and 180-150=30
Hope this helps

Step-by-step explanation:
Answer:
1. 375
2. 294
Step-by-step explanation:
Area of a trapezoid
A = 1/2 (b1+b2) *h where b1 and b2 are the top and bottom of the trapezoide
1.
A = 1/2 (14+36) *15
= 1/2 (50)*15
= 25*15
375
A = 1/2 (21+7) *21
= 1/2 (28)*21
= 14*21
294
