<u>Answer</u>
59°
<u>Explanation</u>
There are 2 parallel line and one transverse.
Angles in a straight line add up to 180°
∴ 180 - (2a + 3) = 180 - 2a -3
= 177 - 2a
The angle (177 - 2a) corresponds to angle a in the diagram. The two corresponding angles are equal.
∴ 177 - 2a = a
177 = a + 2a
3a = 177
a = 177/3
= 59°
Each angle on a triangle pertains to the opposite side
so let’s start by solving the equations:
6 + 4 = 10
2(6) - 3 = 9
3(6) - 10 = 8
then order then look at what each of the sides is opposite to:
10 = A
9 = B
8 = C
so from smallest to largest the angles are C, B, A
Answer:
1.75 meters² or 175 centimeters²
Step-by-step explanation:
Step 1: Find Area of the Base.
- Base is a square with dimensions of 7cm by 7cm
Step 2: Find the Area of the Triangles.
- Each triangle has a base of 7cm and a height of 9cm.
- 7 x 9 = 63, and 63/2 = 31.5
- 31.5 x 4 = 126 cm²
Step 3: Add the areas together.
- 175 cm²
Thus, the surface area is 1.75 m^2 or 175 cm^2.
Steve ran 11 miles
let the distance Steve ran be x
Then distance Kevin ran is x + 4 ( 4 miles more than Steve )
x + x + 4 = 26 ( the sum of their distance is 26 )
2x + 4 = 26 ( subtract 4 from both sides )
2x = 22 ( divide both sides by 2 )
x = 11
Steve ran 11 mies and Kevin ran 11 + 4 = 15 miles
check 11 + 15 = 26
