Answer:
The measure of the 2 angles are 90° and 35°.
Step-by-step explanation:
The sum of angles in a triangle is 180°.
2x + x - 10 + 55 = 180
Simplify.
3x + 45 = 180
Find 3x.
3x = 180 - 45
= 135
Find x.
x = 135 ÷ 3
x = 45
2x° = 45° × 2
= 90°
(x-10)° = 45° - 10°
= 35°
Answer:
141
Step-by-step explanation:
So we substitute x with 6
5*6^2+2*6-10
5*36+12-10
180+2
182
then substitute x with 3
5*3^2+2*3-10
5*9+6-10
45-4
41
now we find the difference
182-41=141
Answer:
The groups walking speed is or
Step-by-step explanation:
we know that
To find the speed divide the distance by the time
so
Convert to mixed number
We can solve this problem by setting up a proportion. When creating the proportion it is important to keep the units aligned. Our proportion would look like this:
We are looking for x, the amount of sugar she needs with 40% sugar syrup. To solve, we can cross multiply and divide. We cross multiply 10 x 40, then divide by 25:
10 x 40 = 400
400/25 = 16
Ms. Maryna needs 16 lbs of sugar to make 40% sugar syrup.
