First, write an equation system for the problem
For example, x represents the first angle and y represents the second angle
An equation for "t<span>he measure of an angle is seventeen times the measure of a complementary angle" is
</span>∴ <span>x = 17y
The sum of complementary angle is 90</span>°. It can be written as<span>
</span>∴ x + y = 90°
<span>
Second, use subtitution method to find the value of x and y
Subtitute x with 17y
x + y = 90</span>°
17y + y = 90°
18y = 90°
y = 90°/18
y = 5°
Subtitute y with 5°
x = 17y
x = 17(5)
x = 85°
The measure of each angle is 5° and 85°
Answer:
r = 21 cm
Step-by-step explanation:
The radius of a circle is 1/2 of the diameter
r = 1/2d
r = 1/2(42)
r = 21 cm

Answer:
66 tens - 38 tens= 58 tens
Step-by-step explanation:
You will start off by making the 6 in the ones place a 16 since you can't subtract 6-8 and change the 6 in the tens to a 5 since you borrowed. Hope this helps! :)
