Find the area of the triangle. round the answer to the nearest tenth.

Option A

Step-by-step explanation:

Area of a triangle with two sides and one acute angle is represented by

Area = (side1) (side2)

where θ is an angle between the side.

Side 1 = 13 [given]

Side 2 = 13 [given]

Since ∠EDF = 63°

So ∠EFD = 63° [ equilateral triangle]

Therefore, ∠DEF = 180 - [63 -63]

                              = 180° - 126°

                             = 54°

Now area will be A = 13 × 13 ×

                               = 68.36 ≈ 68.4 square units.

Option A is the answer.

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
