Step-by-step explanation:
4. To use SSS, you need three pairs of congruent sides. You're given two pairs of congruent sides, so the additional information needed is WY ≅ KM.
5. To use ASA, you need a pair of congruent sides between two pairs of congruent angles. You're given one pair of congruent angles, and since the triangles share a common side, we know BC ≅ BC. So the additional information needed is ∠WBC ≅ ∠ACB.
6. To use SAS, you need a pair of congruent angles between two pairs of congruent sides. You're given two pairs of congruent sides, so the additional information needed is ∠I ≅ ∠F.
Answer:
45
Step-by-step explanation:
Slope = change in Y / change in x
Slope = (-2 - -2) / (-9 - -1)
Simplify:
Slope = 0/-8 = 0
Slope = 0
Answer:<-26, 26>
Step-by-step explanation: <4(-5), 4(2)> and
<3(-2), 3(6)>
<-20, 8> and <-6, 18>
Now add <(-20+(-6)), (8+18)>
<-26, 26>
Answer:
7.
lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²
curved surface area=2[area oftraingle]=2×1/2×4×3
=12cm²
now
total surface area=72cm²+12cm²=84cm²
8.
volume of traingular prism=area of traingle ×length
=1/2×12×3.4×4=81.6cm³
