Accepted Solution

A:

Answer:The measure of angle A is 115°Step-by-step explanation:we know thatThe sum of the internal angles of a triangle must be equal to 180 degreesso∠C+∠A+∠B=180°substitute values and solve for xx°+(3x-35)°+(x-35)°=180°5x°=180°+70°x=250°/5=50°Find the measure of angle A∠A=(3x-35)°substitute the value of x∠A=(3(50)-35)=115°
