Answer:
x = 8
Step-by-step explanation:
Given
- 2(- 3x + 3) + 2x = 58 ← distribute and simplify left side
6x - 6 + 2x = 58
8x - 6 = 58 ( add 6 to both sides )
8x = 64 ( divide both sides by 8 )
x = 8
Answer:
Option 2 : m∠1 = 67.4°, m∠2 = 104.5°
Step-by-step explanation:
Lets find the measure of angle 2 first:
180° - 17.3° - (180° - 121.8°) = Angle 2
↑
Angle of the straight line = 180°
The angle should be 180 - 121.8
Angle 2 = 104.5
At this point the only answer that works is the second option, but let's still work out Angle 1
Angle 1 :
Theory of opposite angles state that the opposite angles inside a triangle = the exterior angle
in this case:
Angle 1 + 37.1 = Angle 2
Since we know angle 2 = 104.5, lets solve
Lets say angle 1 = x
x + 37.1 = 104.5
x = 104.5 - 37.1
x = 67.4

Answer:
47 cm.
Step-by-step explanation:
Alex, Bruno, and Charles each add the lengths of two sides of the same triangle correctly.
They get 27 cm, 35 cm, and 32 cm, respectively. Find the perimeter of the triangle, in cm
find:
Find the perimeter of the triangle, in cm. What is the most efficient strategy you can find to solve this problem?
<u>solution:</u>
27, 35, and 32 are each the sum of a different pair of sides of the triangle
Then 27 + 35 + 32 is the sum of all three sides, each counted twice.
Thus, 27 + 35 + 32 = 94 is twice the perimeter
therefore,
the perimeter of the triangle is 94/2 = 47 cm.
