Two streets form an intersection. angle c and angle d are supplementary angles. if the measure of angle c is 128 degrees and the measure of angle d is times the value of x. what is the value of x

d) the triangle is a right triangle 60 squared +144 squared= 156 squared

step-by-step explanation:

156 squared is the hypothenuse

so 156= c

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
