Answer:
x = 34°
Step-by-step explanation:
Given AC and BD are perpendicular bisectors, we can say that at point E, there are 4 right angles [perpendicular bisectors intersect to create 4 90 degree angles].
Now, if we look at the triangle AED, we know that it is a right triangle, meaning that angle E is a right angle.
Also,
We know sum of 3 angles in a triangle is 180 degrees. Thus, we can write:
∠A + ∠E + ∠D = 180
<em>Note: Angle A and Angle D are just the half part of the diagram. More exactly we can write:</em>
∠EAD + ∠ADE + ∠DEA = 180
Given,
∠EAD = 56
∠DEA = 90
We now solve:
∠EAD + ∠ADE + ∠DEA = 180
56 + ∠ADE + 90 = 180
146 + ∠ADE = 180
146 + x = 180
x = 180 - 146
x = 34°
Answer:
v^3 (v-cubed)
Step-by-step explanation:
1. Cross multiply/cross out all common denominators
2. Then simplify and multiply
Answer:
Step-by-step explanation:
They tell you the answer in the picture. Angle DAB is the lower left vertex, so its measure is 80°
Angle BCD is the upper right vertex.
The number is x
product of 3 and the x = 3x
four more = 3x + 4
(a+b+c)^3=a^3 +b^3+c^3-2(ab+ac+bc)
216=a^3+b^3+c^3-2(11)
a^3+b^3+c^3=238
but ıdk how can ı find -3abc :/
