NEED HELP! I ALREADY DID HALF, BUT STILL CONFUSED!

Mathematics
1 answer:
Anna35 [415]3 years ago
8 0

Answer:

Step-by-step explanation:

Triangle BCZ is a right angle triangle. Triangle BCU is also a right angle triangle. Side BU is common to both triangles.

To determine m∠ZBC, we would apply the tangent trigonometric ratio.

Tan θ = opposite side/adjacent side. Therefore,

Tan B = 8/6 = 1.33

m∠ZBC = Tan^-1(1.33) = 53.06

m∠UBC = m∠ZBC/2 = 26.53

To determine CU, we would apply

the tangent trigonometric ratio.

Therefore,

Tan 26.53 = CU/6

CU = 6Tan26.53

CU = 6 × 0.4992

CU = 2.9952

What percent of $375 is $11.25 and what percent of $56.25 is $11.25?
Angelina_Jolie [31]

Answer:

3%percent of $375 is $11.25 and 20% of $56.25 is $11.25 .

Step-by-step explanation:

Formula

Percentage = \frac{Part\ value\times 100}{Total\ values}

First Part

As given

Total value = $375

Part value = $ 11.25

Put values in the formula

Percentage = \frac{11.25\times 100}{375}

Percentage = \frac{1125}{375}

Percentage = 3 %

Second Part

Total value = $56.25

Part value = $11.25

Put the values in the formula

Percentage = \frac{11.25\times 100}{56.25}

Percentage = \frac{1125}{56.25}

Percentage = 20%

Therefore 3%percent of $375 is $11.25 and 20% of $56.25 is $11.25 .
