<em>x = 4</em>
<em>Here is why:</em>
When adding up all angles of a triangle, they will be equal to 180.
Let's add ∠B and ∠C together.
Let's subtract it from 180, that will be the value of ∠A.
Now we can set ∠A equal to 49.
Subtract 9 from both sides.
Divide.
<u>x = 4</u>
3 x $9.25 = 27.75
4/8 = 9.25/2 = 4.6 so 27.75+ 4.6 equals 32.37 (so I’ve only done 4/8 so far but it states it’s 7/8 so we’re gonna go ahead and add 2/8 of it more so that it’s 6/8) therefore we know 4/8 is 4.6 we’ll divide that by 2 to get 2/8 and that would be 2.3 so 32.37 + 2.3 equals 34.67 Nd we do the same again with the remainder additional 1/8 since we know 2/8 is 2.3 then we divide it by two that would 1.15 so 34.67+ 1.15 equals 35.81 and the closest answer is D
Percent increase = (new number - original number) / original number...* 100
= (26 - 14) / 14 ...* 100
= 12/14 * 100
= 1200/14
= 85.7% <==
Step-by-step explanation:
Sum of opposite angles are supplementary,
x + 60 + 3x = 180
4x + 60 = 180
4x = 180 - 60
4x = 120
x = 120 / 4
x = 30
