What is the area of an equilateral triangle that has sides of 2 yards and a height of 4.25 feet?

The first thing you need to do is convert the yards into feet. In one yard there are three feet. So 2*3=6 now you can do the triangle area equation.
6*4.25=25.5 then divide by two. 25.5/2=12.75
So the area of the triangle is 12.75 ft^2

1. When Profit percent and Cost price are given , $\large{ \tt{SP = \frac{CP(100 + P\%)}{100}}}$

2. When Loss% & Cost price are given , $\large{ \tt{SP = \frac{CP(100 - L\%)}{100}}}$

3. When Profit / Gain percent and Selling price are provided , $\large{ \tt{CP = \frac{SP \times 100}{100 + G\%} }}$

4. When Loss % & SP are provided , $\large{ \tt{CP = \frac{SP\times 100}{100 - L\%}}}$

Choices for Question #1:

hodyreva [135]

Answer:

Question #1 choice A x=3, ST=24 and Question #2 choice C x =12

Step-by-step explanation:

Question #1

T midpoint so ST=TU and 8x = 2x+18

8x =2x+18

8x-2x=18

6x=18

x=18/6

x=3

so ST= 8x=8*3=24

choice A

Question #2

M midpoint of AB so AM=MB and 4x+1=7x-35

4x+1=7x-35

1+35=7x-4x

36=3x

36/3=x

12=x

choice C

Solve the triangle. Round your answers to the nearest tenth.

Rasek [7]

Answer:

m∠A ≈ 43°

m∠B ≈ 55°

mBC ≈ 20

Step-by-step explanation:

Law of Sines: $\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

Step 1: Find m∠B

$\frac{29}{sin82} =\frac{24}{sinB}$

Step 2: Solve for ∠B

29sinB = 24sin82°

sinB = 24sin82°/29

B = sin⁻¹(24sin82°/29)

B = 55.038°

Step 3: Find m∠A

180 - (55.038 + 82)

180 - 137.038

m∠A = 42.962°

Step 4: Find BC

$\frac{29}{sin82} =\frac{BC}{sin42.962}$

Step 5: Solve for BC

29sin42.962° = BCsin82°

BC = 29sin42.962°/sin82°

BC = 19.9581
