Answer:
x = 13
∠F = 28°
∠S = 28°
y = 9
DE = 38 ft
Step-by-step explanation:
We are told that △DEF = △QRS
Looking at both triangles and by comparison, it is clear that;
∠R = ∠E = 123°
∠Q = ∠D = 29°
∠S = ∠F = 180 - (123 + 29) = 28°
Also,QR = DE
Thus; 5y - 7 = 38
5y = 38 + 7
5y = 45
y = 45/5
y = 9
Thus,y = 9 and DE = 38 ft
We see in the image that ∠S = (2x + 2)°
From earlier we deduced that ∠S = 28°
Thus; 2x + 2 = 28
2x = 28 - 2
2x = 26
x = 26/2
x = 13
Answer:
C.
Step-by-step explanation:
The answer is c (x+21) and (x-2) you have to find two numbers that multiply yo give you -42 and add to give you 19
Step-by-step explanation:
plug the coordinate points into the equations and solve for the remaining variable.
b) (2,3) - 5(2) + b(3) = 16
10 + 3b = 16. 3b= 6. b = 2
(0,8) - 5(0) + 2(8) = 16. 0+ 16 = 16. ☆
a) (4,4) assume based on results you meant y squared. (y^2)
(4)^2 = 4k. 16 = 4k. k = 4
(8)^2 = 4(16). 64 = 64. ☆
