1/4 + 3/10 = 10/40 + 12/40 = 22/40
40/40 = 22/40 = 18/40
18/40 = cranberry j
Ratio=
A : O : C
10/40 : 12/40 : 18/40
0.25 : 0.3 : 0.45
Answer:
140°
Step-by-step explanation:
The sum of angle of a triangle is equal to 180°.
Two of the angles measured 20°.
We need to find the measure of the third angle of Nora’s triangle. let the third angle is x. So,
20+20+x = 180
40+x = 180
x = 180-40
x = 140°
So, the third angle of the triangle is 140°.
The number that equals 280 tenths + 19 thousandths is 28.019
<h3>How to determine the number?</h3>
The statement is given as:
280 tenths + 19 thousandths
Rewrite the terms of the expression as fractions
So, we have
280/10 + 19/1000
Evaluate the quotients
28.0 + 0.019
Add both numbers
28.019
Hence, the number that equals 280 tenths + 19 thousandths is 28.019
