Question

plz help me find a c d with process

Answer 1

Answer:

c) 40 and 50

d) 60, 90 and 30

Step-by-step explanation:

c) 90+a+a+10=180 (sum of triangle)

Ans. 2a+100=180

2a=180-100

2a/1=80

a=80/2

a=40

Value of a=40

Value of first angle= a = 40

Value of 2nd angles= a+10 = 50

(btw in c part 90 is the square on the bottom left every time you see it, its value is 90. And I cross multiplied when I put 1 under 2a every value which has no denominator is automatically given the denominator 1)

d) 2x+3x+x=180 (sum of triangle)

Ans. 6x/1=180

x=180/6

x=30

Value of 2x= 2(30)=60

Value of 3x= 3(30)=90

Value of x= 30
