In an isosceles triangle, the base angles are congruent. The third angle is called the vertex angle.
Here, the vertex angle is <A.
Therefore, m<C = m<B.
m<A = 3m<B + 20
m<A + m<B + m<C = 180
3m<B + 20 + m<B + m<B = 180
5m<B + 20 = 180
5m<B = 160
m<B = 32
m<C = m<B = 32
Answer: m<C = 32 deg
The sum of the length of the two sides of the triangle must be greater than the length of the third side. None of the triangles is formed. Then option A is correct.
<h3>What is the triangle?</h3>
Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
The sides of the triangle are 4.7 m, 1.6 m, and 2.9 m.
The condition will be

We know that the sum of the length of two sides of the triangle must be greater than the length of the third side.
Hence, none of the triangles is formed.
Thus, option A is correct.

Any object when rotated by 360°, will look exactly the same
Answer:

Step-by-step explanation:
Jeremy rides a Ferris wheel. The graph shows h, Jeremy’s height above the ground at any time during the ride
Number line represents the height above the ground at any time during the ride.
the shaded part of the graph lies between 10 and 50, also we have solid dot at 10 and 50.
So height of the inequality is
