Answer would be the bottom answer
Answer:
∠E = 146°
Step-by-step explanation:
- an isosceles triangle has both two equal sides and two equal angles
- the sum of the interior angles of a triangle is 180°
- the measure of third angle = the sum of the interior angles - the sum of two angles
E = 180 - (71 + 71) = 146
∠E = 146°
114 was 3 less than 1/3 of the novel
114=-3+1/3(novel)
find (novel)
add 3 to both sides
114+3=3-3=1/3(novel)
117=0+1/3(novel)
117=1/3(novel)
times both sides by 3/1
351=(3/3)(novel)
351=novel
351 pages in the novel
