Answer:
1: 130
2: 70
Step-by-step explanation:
Supplementary angles add up to equal 180
So to find the measure of the missing angles, we subtract the measure of the known angles from 180
For #1
∠B = 180 - 50
180 - 50 = 130
Hence ∠B = 130
For#2
∠D = 180 - 110
180 - 110 = 70
Hence, ∠D = 70

Answer:
4(2qp + 5qr - 4s)
Step-by-step explanation:
8pq + 20qr – 16s
we can use 4 as a common factor between these numbers.
8/4 = 2
20/4 = 5
16/4 = 4
so
4(2qp + 5qr - 4s) is the most factorized answer we can get
Answer: f(-3) = 9
Step-by-step explanation:
Plug in -3 for x
f(-3) = (-3)^2
Square -3
(-3)^2 = 9
Answer:
2
Step-by-step explanation:
From the diagram attached :
AB = AD + BD = 3t + 3t = 6t
BC = BE + EC = 4t + 4t = 8t
AC = 7t + 6
Perimeter of the triangle = 48
Perimeter of a triangle (P) :
P = AB + BC + AC
48 = 6t + 8t + 7t + 6
48 - 6 = 6t + 8t + 7t
42 = 21t
t = 42 / 21
t = 2
