Step-by-step explanation:
measure of exterior angle = sum of measures of remote interior angles
p + p - 8 = p + 38
2p - 8 = p + 38
p - 8 = 38
p = 46
The answer is 4x cm < h < 10x cm.
The third side of the triangle is greater than the difference of the lengths of the other two sides (h > 7x cm - 3x cm) and it is less than the sum of the lengths of the other two sides (h < 7x cm + 3x cm)<span>. Therefore:
</span>h > 7x - 3x<span>
h < 7x + 3x
</span>
This can be expressed as:
7x cm - 3x cm < h < <span>7x cm + 3x cm
</span>⇒ 4x cm <span>< h < 10x cm</span>
