Answer:
27, 20
Step-by-step explanation:
x + y = 47
x - y = 7
if we solve the second equation for 'x' we can:
let 'x' = y+7
substitute that expression for 'x' in the first equation to get:
y+7 + y = 47
2y = 40
y = 20
now find 'x':
x - 20 = 7
x = 27
Answer:
x = 22
y = 24
Step-by-step explanation:
110 and 5x are equal to each other because they are vertically opposite of each other.
110 = 5x; divide 5 on both side; x = 22
a line is 180 degrees, so if we use angle 110 with 3y-2, then 3y-2 must equal 70 (180 - 110).
70 = 3y - 2; add 2 to both sides
72 = 3y; divide 3 on both sides; x =24
Answer: the answer is t= 9/5
Step-by-step explanation:
Answer: (1) D. BE ≡ AD
(2) B. AAS Postulate
(3) B. RF
<u>Step-by-step explanation:</u>
1) Place the letters underneath each other and match them up
B A E
D E A
∠B = ∠D ∠A = ∠E ∠E = ∠A
BA ≅ DE AE ≅ EA BE ≅ DA
2)
∠V = ∠Y Angles are congruent (given)
∠VWZ = ∠YWZ Angles are congruent (def of ∠ bisector)
WZ = WZ <u> Sides are the same (reflexive property</u>)<u> </u>
ΔWZV ≡ ΔWZY Angle-Angle-Side (AAS) Postulate
3) F ∴__________________∴ R
Segment FR = RF is between ∠F and ∠R
