Answer 1

Step-by-step explanation:

=10+x+x=90 ( complementary angles add up to 90 degrees)

= 2x +10=90(x+x is 2x)

= 2x=90-10 is 80 (10 goes to the other side it becomes -10)

= 2x=80, x=80/2 which is 40

Now, as they differ with 10 degrees add 40 +10=50

50+40=90

Hence the measure of smaller angle is 40 degrees

Hope it helps you:)

Answer 2

Answer:

B

Step-by-step explanation:

let the angles be x and x+ ten degrees

x+x+9+1 = ninety

2x = eighty

thus, x= smaller angle = choice B= forty degrees
