Answer:
∠TRS = 68°
Step-by-step explanation:
∠TRS + ∠S = 180 - 44 = 136
∠TRS = ∠S
2∠TRS = 136
∠TRS = 68
Answer:
Hi! I'll do my best to explain for you.
-6(2x-3)+2x =0 First, set the equation equal to zero.
-12x+18+2x=0 Then, distribute the -6 by multiplying it with the -2 and -3.
-10x+18=0 Combine the like terms, which are -12x and 2x, to get -10x.
-10x=-18 You want to get the x on 1 side. Subtract 18 from both sides.
x=-18/-10 Divide by -10 on both sides.
x=1.8 Simplify the fraction. The answer is x=1.8.
I hope this helped!
Answer:
Step-by-step explanation:
We are told that the perimeter is 48 = 2L + 2W. This reduces to
24 = L + W. Next, substitute, one by one, the 3 widths 10 cm, 3.6 cm and w cm:
a) If W = 10 cm, 24 = L + W becomes 24 = L + 10, or L = 14 cm
b) If W = 3.6 cm, 24 = L + W becomes 24 = L + 3.6, or L = 20.6 cm
c) If W = w, 24 L + W becomes 24 = L + w, so that L = (24 - w) cm
