Question

plz solve all the questions step by step​

Answer 1

Answer:

1) 60 degrees

2) 65 degrees

3)40 and 50 degrees

4)84 and 96 degrees

5) 160 degrees

Step-by-step explanation:

1)x and x+30 are two angles which are complementary, meaning they add upto 90 degrees.

=> x + x + 30 = 90

2x= 60

x = 30

2)z +z + 50 = 180

z= 65

3)let the angles be 4x and 5x

4x+5x=90

9x=90

x=10

therefore, 4 x 10 , 5 x 10 = 40, 50

4) let the angles 7y, 8y

7y+8y=180

15y = 180

y = 12

7 x 12, 8 x 12

= 84, 96

5) complementary angle of 50 = 40

25% of the given angle = 40

25/100 x X = 40

X = (40 x 100)/25

=160 degrees.
