Answer:
?
Step-by-step explanation:
The possible value of b is:
-ax + 12x + 32 /over/ a + x
My answer would be 65° because none of the other choices make sense!
This angle is clearly under 90°, which eliminates the choices of 92° and 138°. This angle is also clearly bigger than 27°, which eliminates this choice too!
I really hope this helped, if there’s anything just let me know! ☻
Answer:
54 sq units
Step-by-step explanation:
The triangle at the top (FAB) has a base of 10 and a height of 3. Area of triangle is 1/2bh so 1/2(10 * 3) = 1/2 * 30 = 15 sq units
If you cut off the triangle you have a trapezoid, EBCD. A trapezoid is (b1 + b2)/2 * h, so (6 + 7)/2 * 6 = 13/2 * 6 = 6.5 * 6 = 39 sq units
Add them together: 15 + 39 = 54 sq units
