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°
Y-5=3(x+1)
y-5=3x+3
add 5 to both sides
the answer would be y=3x+8
Answer:
a. 38 you got it right
b. is provided below
Step-by-step explanation:
b. so 2/5 is .4 so 14.4 and then 3/8 is .375 and so all we need to do is divide those. 14.4 / .375 and we get 38.4.
2/5= 0.4 14.4 3/8= .375 14.4/0.375 =38.4
