75°
The angles adjacent to A and B are 180° - 105° = 75°
These adjacent angles are the other alternate interior angles
Width = 3x
Length = x
3x + x = 4x
56 / 4 = 14
x = 14
14 x 3 = 42
Answer: 42 meters
Hope it helped :)
Answer:
x ≈ 36.2
Step-by-step explanation:
Since the legs are congruent then the triangle is isosceles.
The altitude bisects the base and divides the triangle into 2 right triangles.
Using the right triangle on the right with legs 33 and 15
Apply Pythagoras' identity to the right triangle, that is
x² = 33² + 15² = 1089 + 225 = 1314 ( take the square root of both sides )
x =
≈ 36.2 ( to 1 dec. place )
There are 2 angle measurements not identified.
Angle ACB and angle ABC.
To find angle ACB you need to know that a straight line is 180 degrees, so if the angle to the right is 131, the angle to the left (Angle ACB) must be 49 degrees.
To find angle ABC, you need to know that the sum of all 3 angles in a triangle equal 180 degrees, so 180 - (49 + 44) = 87 degrees. Angle ABC is 87 degrees.
Answer: A. 88 turtles
To find this, multiple 110 x .80
This is easier than multiplying 110 by .20 because you don’t have to subtract.
110 x .80 = 88
