Answer:
B) 81°
Step-by-step explanation:
Given:
From the figure given below,
∠1 = 3x + 18
∠7 = 2x + 39
∠1 and ∠7 are a pair of exterior alternate angles. For two parallel lines l and m, cut by a transversal n, the pair of exterior alternate angles are congruent to each other.
Therefore, the angles 1 and 7 are congruent to each other. This gives,
∠1 ≅ ∠7

Therefore, the value of 'x' is 21.
Now, the measure of angle 7 can be calculated by plugging in the value of 'x' in the expression for angle 7. This gives,

Therefore, the correct option is option (B).
g(n) = 3n³ - 5 h(n) = 2n - 5 (g + h)(2) = g(2) + h(2)
g(2) = 3(2)³ - 5 = 3(8) - 5 = 24 - 5 = 19
h(2) = 2(2) - 5 = 4 - 5 = -1
g(2) + h(2) = 19 + -1 = 19 - 1 = 18
Answer: 18
Answer:
Step-by-step explanation:
y - 4 = -(x - 2)
y - 4 =-x + 2
y = -x + 6
This is just my guess but I want to say no they are not similar because the first 10 + 5 = 15
8 + 5 = 13 not 12
To make it similar, 8 needs to be 7. This is ONLY my guess, I’m not 100% confident in my answer
18/12=22.50/n
