Answer:
∠ 3 = 60°
Step-by-step explanation:
∠ 1 and ∠ 2 are same- side interior angles and sum to 180° , then
4x + 36 + 3x - 3 = 180
7x + 33 = 180 ( subtract 33 from both sides )
7x = 147 ( divide both sides by 7 )
x = 21
Then
∠ 2 = 3x - 3 = 3(21) - 3 = 63 - 3 = 60°
∠ 2 and ∠ 3 are alternate angles and are congruent, so
∠ 3 = 60°
Three runners will be needed. 1/3 is .3 and 1/9 is .1 since they all need to do 1/9 of a mile that makes the answer 3.
Answer:
7
Step-by-step explanation:
first you get <u>the area of the square which is 4</u> then you get the area of the triangle which would be 3 because <u>2x3=6 then divide by 2 </u>because its a triangle and add the areas of both and its 7
hope this helps ^_^
