Answer 2

Answer:

Two less than 4 times a number is the same as the number plus 34. Find the number. One of the angles of an isosceles triangle is 100 degree.Is this a base angle or a vertical angle? Calculate the other two angles also.

Step-by-step explanation:

Let the base angles be

′

x

′

Therefore,

x+x+40

∘

=180

∘

[Given]

2x=180

∘

−40

∘

2x=140

∘

x=70

∘

Hence,

The base angles of the triangle are 70
