Answer:

60°

Step-by-step explanation:

sum of interior angles of quadrilateral is 360°

∠C = 70°

∠D = 50°

∠C + ∠D = 120°

∴ ∠A + ∠B = 360° - 120° =240°

AO and BO bisect ∠A and ∠B

∠OAB + ∠OBA = 1/2 x ( ∠A + ∠B) = 120°

∠AOB = 180° - (∠OAB + ∠OBA) = 180° - 120° = 60°

The two triangles are similar.
Andrei [34K]

Answer:

x=10

Step-by-step explanation:

The two triangles are similar since each triangle is the same shape of right triangle but different sizes. To find x, write a proportion between two equal ratios of side lengths.

\frac{28}{20}=\frac{4x+2}{3x}

Solve by cross multiplying.

28(3x) = 20(4x+2)

84x = 80x + 40

4x = 40

x=10

spayn [35]

Answer:

\large \boxed{\mathrm{served \ a \ greater \ variety \ of \ ages}} \\ \\ \large \boxed{\mathrm{range}}

Step-by-step explanation:

Restaurant A <u>served a greater variety of ages</u> than Restaurant B, because the <u>range</u> of data for Restaurant A is greater than that of Restaurant B.

Range of a data set is the data spread.

Restaurant A is serving a greater variety of ages of people since it has a higher range than that of Restaurant B.
