What is the area of the triangle shown below

Mathematics

Answer:

B

Step-by-step explanation:

Preliminary

From A, drop a perpendicular to the line BC.

The line BC has to be extended to your right.

Call the intersection point D.

Find angle ABD

ABD and ABC = 180                   They are supplementary angles.

140 + ABD = 180

ABD = 40

Find AD

Sin(theta) = AD/AB

AB = 25

Theta = 40

Sin(theta) = AD / 25

Sin(40) = 0.6428

0.6428 = AD / 25                       Multiply both sides by 25

AD = 25*0.6428

AD = 16.07

Find the Area of ABC.

The height = 16.07

The base = 40 m

Area = 40*16.07 / 2

Area = 321.4 m^2

Which of the pairs of angles are vertical angles and thus congruent? ∠A and ∠G ∠A and ∠B ∠C and ∠F ∠D and ∠H
r-ruslan [8.4K]

Answer:

∠A and ∠G is the pair of vertical angles.

Step-by-step explanation:

From the figure attached,

Two lines 'm' and 'n' are two parallel lines. These lines intersect a horizontal line 'l'.

Since, "Pair of opposite angles formed at the point of intersection are the vertical angles and equal in measure."

Therefore, Opposite angles ∠A ≅ ∠G, ∠B ≅ ∠H, ∠C ≅ ∠E and ∠D ∠F are the vertical angles.

From the given options,

∠A and ∠G is the pair representing the pair of vertical angles and thus congruent.
