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°
One moment, i wills answer soon working on it
we have
Solve for w means that clear variable w
Group terms that contain the variable w, and move the other terms to the opposite side of the equation
Factor the variable w
Divide both sides by 
therefore
<u>the answer is</u>
The y-intercept is 28, while the slope is
I did this by moving the x to left, then dividing everything by 4.
Answer:
Step-by-step explanation:
Let us find the acceleration of box .
v² = u² + 2as
Putting the values
7² = 3² + 2 a x 14
a = 1.43 m /s²
If coefficient of friction be μ
force of friction = μ mg
= μ x 10 x 9.8
= 98μ
Net force pushing the box
= 85 - 98μ
Applying newton's second law
85 - 98μ = 10 x 1.43
98μ = 85 - 14.3
μ = .72
