Answer:
A = 14 m^2
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2) *h where b is the length of the bases and h is the height
A = 1/2 (2+5) *4
A = 1/2(7)4
A = 14 m^2
Answer:
∠ 1 = 130°, ∠ 2 = 50°
Step-by-step explanation:
∠ 1 and 130° are alternate angles and congruent, so
∠ 1 = 130°
∠ 2 and 130° are same- side interior angles and are supplementary, so
∠ 2 + 130° = 180° ( subtract 130° from both sides )
∠ 2 = 50°
The diameter of the circle is 17.49
Answer:
14
Step-by-step explanation:
The law of cosines is a² = b²+c²-2bc(cos A).
We will use s in place of a, since it is the unknown side. This makes b and c 8 and 9.
Angle A will be the angle opposite side a, or in this case side s. This makes it 111.
This gives us
s² = 8²+9²-2(8)(9)(cos 111)
s² = 64+81-2(8)(9)(cos 111)
s² = 145-144(cos 111)
s² = 196.605
Take the square root of each side:
√(s²) = √(196.605)
s = 14.02 ≈ 14
