Answer:

30°

Step-by-step explanation:

Suppose smaller angle = x°

larger angle = (2x+90) deg

Supplementary angles so sum = 180 degree

x+2x+90=180

3x+90=180

3x=180-90

3x=90

x=30

larger angle =2x+78=68+78=146 degree

Smaller angle = 30°

Hope this answer helps you :)

Answer:

30, 150

A + B = 180

A = 2B+ 90

2B + 90 + B = 180

3B = 90

B=30 A=150

If 10a+10b=35, what is the average (arithmetic mean) of a and b?

worty [1.4K]

Answer:

1.75

Step-by-step explanation:

If a and b are two numbers, then their arithmetic mean is

$\dfrac{a+b}{2}$

Given:

$10a+10b=35$

Divide this equation by 10:

$a+b=3.5$

Now, divide it by 2:

$\dfrac{a+b}{2}=\dfrac{3.5}{2}\\ \\\dfrac{a+b}{2}=1.75$
