Answer:

a. 138 + x = 180

Step-by-step explanation:

which equal 138

and x being the missing angle

finally the total of all angles in a triangle = 180

I need help with 25 and 26
valina [46]

25.

The area is b * h, so

(2x + 7) * 4

which is greater than 100 units, so

(2x + 7) * 4 ≥ (don't look at =; only major) 100

8x + 28 ≥ 100

8x ≥ 100 - 28

8x ≥ 72

x ≥ 9

26.

The perimeter is 2 * (b + h), so

2 * (2x + 7 +4) = 2 * (2x + 11)= 4x + 22

which is greater than 50 units, so

4x + 22 ≥ (don't look at =; only major) 50

4x ≥ 50 - 22

4x ≥ 28

x ≥ 7
