A = 1/2 hb
20 = 1/2 x 4 x b
20 = 2 b
b = 20 /2
b = 10
answer is <span>10 m</span>
Angle A = 130° and Angle B = 110°
Solution:
Given ABCD is a trapezoid with ∠C = 70° and ∠D = 50°
If ABCD is a trapezoid, then AB is parallel to CD.
AD is a transversal to AB and CD and
BC is a tranversal to AB ad CD.
Sum of the interior angles on the same side are supplementary.
∠A + ∠D = 180°
⇒ ∠A + 50° = 180°
Subtract 50° on both sides to equal the expression.
⇒ ∠A = 180° – 50°
⇒ ∠A = 130°
Similary, ∠B + ∠C = 180°
⇒ ∠B + 70° = 180°
Subtract 50° on both sides to equal the expression.
⇒ ∠B = 180° – 70°
⇒ ∠B = 110°
Hence, angle A = 130° and angle B = 110°.
Answer:
4:3
Step-by-step explanation:
Think of it like this:
4 beagles to 3 golden retrievers
4 beagles : 3 golden retrievers
4 : 3
Just take out everything but the numbers.
Answer:
6 ways
Step-by-step explanation:
The way to solve for this is to use the formula
Combination C (n-1, r-1)
= n = 5 identical fruits
r = 3 bowls
So, we have: 5 - 1 = 4
3 - 1 = 2
= 4!/2! (4-2)!
= 4 × 3 × 2 × 1/(2 × 1 )(2 × 1)
= 6 ways
