Answer:
sum of interior angles of octagon is 1080 degrees
From figure ,
136 + 132 + 129 + 116 + 158 + 141 + 124 + x = 1080
so, x = 1080 - 936
= 144
Step-by-step explanation: Simply add the angles and substract the sum from 1080 which is the sum of interior angles of octagon
You can do this on a calculator if you search up online radius and height measurement calculator.
Answer:
bisector
Step-by-step explanation:
A <u>bisector</u> divides a segment or angle in half.
Answer:
1200 ounces
Step-by-step explanation:
How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?
Let us represent
Number of ounce of 10% copper = x
Hence, our Equation =
x × 10% + 600 × 70% = (x + 600) × 30%
0.1x + 420 = (x + 600)0.3
0.1x + 420 = 0.3x + 180
Collect like terms
0.3x - 0.1x = 420 - 180
0.2x = 240
x = 240/0.2
x = 1200 ounces
Answer:
The measure of the larger is 
.
Step-by-step explanation:
Given:
The measure of an angle is 
degrees less than three times the measure of another angle.
The two angles are supplementary.
To find: The measure of the larger angle.
Solution:
Let the measure of the smaller angle be 
.
Then the measure of the larger angle be 
.
The two angles are supplementary, so their sum is 
.
So, 
So, the measure of the smaller angle is 
.
And, the measure of the larger angle is 
.
Hence, the measure of the larger is .
