Answer:
Step-by-step explanation:
23.7 < m = 8.3 m > 23.7
Answer:
The proof is given below.
Step-by-step explanation:
Given:
∠WZX ≅ ∠YZX
ZW ≅ ZY
To Prove:
ZX is a perpendicular bisector of WY
Proof:
In Δ WZX and Δ YZX
Statement Reasons
ZW ≅ ZY ……….{Given}
∠WZX ≅ ∠YZX …………..{Given}
ZX ≅ ZX ……….{Reflexive Property}
ΔWZX ≅ ΔYZX ….{Side-Angle-Side test}
WX ≅ YX ....{corresponding sides of congruent triangle or cpct}
∠ZXW ≅ ∠ZXY ...{corresponding angles of congruent triangle or cpct}
But W-X-Y is a straight Line
...Linear pair postulate
∴ WX ≅ YX {ZX bisects WY}
∠ZXW ≅ ∠ZXY = 90° {ZX Perpendicular WY
∴ ZX is a perpendicular bisector of WY
Answer:
When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative.
Answer:
weight of pears sold = 4.08 kg
Step-by-step explanation:
total weight of apples and pears = 6.8 kg
2/5 of this weight = apples
this means that if the total weight (6.8 kg) were divided into 5 parts, apples take 2 out of the 5 parts:
∴ weight of apples = 2/5 of total weight
weight of apples 2/5 × 6.8 = 2.72 kg
Therefore apples weigh a total of 2.72 kg
Therefore, since weight of apples + weight of pears = 6.8 kg
2.72 + weight of pears = 6.8
weight of pears = 6.8 - 2.72 = 4.08 kg
Answer:
x = 11
Step-by-step explanation:
33 divided by 3 is 11, and 11 times 3 is 33.
