  • Measure of angle C = 100°
  • Measure of angle A = 40°
  • We know, sum of all angles of a triangle is 180°.
  • Therefore, the measure of angle B

= [180 - (100 + 40)]° = 40°

  • When two angles of a triangle are equal, then the triangle is isosceles.
  • Here, the measure of angle A and B are equal, i.e., 40°
  • So, ∆ABC is an isosceles triangle.

<u>Answers:</u>

  1. <u>4</u><u>0</u><u>°</u>
  2. <u>Yes</u>

Hope you could get an idea from here.

How many solutions does the system 2y=10x-14 and 5x-y=7 have? need worked out step by step please!
VLD [36.1K]
2y=10x-14
5x-y=7

Divide both sides by 2 in the 1st equation
y=5x-7
Now substitute is to 2nd equation 
5x-5x+7=7
0=0

Therefore there is no solution or it is inconsistent
