Answer:
the answer is 96°
Step-by-step explanation:
it is an isosceles triangle as it's 2 sides are equal.
for an isosceles triangle, the angles made by the equal sides with the third side are equal.
and the sum of all angles in a triangle = 180°
42 + 42 + x = 180
x = 180 - 84
X = 96°
Answer:
<h2>
30° and 150° </h2>
Step-by-step explanation:
α - one angle
2α - two times measure of angle α
2α + 30° - second angle
Paralleogram has two pairs of angles of the same measure.
Sum of interior angles of any quadrangle is 360°
Therefore:
2×α + 2×(2α + 30°) = 360° {divide both sides by 2}
α + 2α + 30° = 180° {subtract 30° from both sides}
3α = 150° {divide both sides by 3)
α = 50°
2α+30° = 2×50° + 30° = 130°
