Answer:
124.5°
Step-by-step explanation:
Let the smallest angle be x. Then, the sum of the angles is an arithmetic sequence with first term x, common difference 7, and 8 terms.
Using the sum of an arithmetic series formula,
So, the third angle is 110.5+14=124.5
<h3>Given : </h3>
- Base of triangle = 8 cm
- Height of triangle = 4 cm
- Area of triangle = ?
As, we have :
- Base of triangle, b = 8 cm
- Height of triangle, h = 4 cm
So, to find area of triangle we have a formula :
Hence, area of given triangle is 16 cm².
