Help me solve for the right triangle

Mathematics
1 answer:
AleksAgata [21]4 years ago
7 0

Answers:

B = 50

a = 10.9

c = 17.0

================================================

Explanation:

This is a right triangle, so the acute angles are complementary, meaning they add to 90

B+40 = 90

B+40-40 = 90-40

B = 50

Also, because this is a right triangle, we can use trig ratios to compute the missing sides

tan(angle) = opposite/adjacent

tan(40) = a/13

a = 13*tan(40)

a = 10.908

a = 10.9

cos(angle) = adjacent/hypotenuse

cos(40) = 13/c

c*cos(40) = 13

c = 13/cos(40)

c = 17.0

note: make sure your calculator is in degree mode

Which graph represents the compound inequality x is less than or equal to 5/4 or x is greater than or equal to 5/2​
In-s [12.5K]

Answer:

Option 2 (Graph B)

Step-by-step explanation:

x ≤ ⁵/4 or x ≥ ⁵/2 represents a compound inequality containing the union of two statements. Either of the statements makes the compound inequality true.

On a graph, the small "o" indicating the start of the value of x would be full, this means ⁵/4 and ⁵/2 are included in the solutions.

Therefore, the correct graph in option 2 (Graph B), where the arrow goes from between 1 and 1.5 to your left, and the other arrow goes from 2.5 to your right.

Find the area of this trapezoid. Be sure to include the correct unit in your answer.14 ft16 ft7 ft17 ft
goblinko [34]

The area of a trapezoid can be found through the formula

A=\frac{a+b}{2}\cdot h

where a and b are the bases and h the height, then,

\begin{gathered} A=\frac{14+7}{2}ft\cdot7ft \\ A=10.5ft\cdot7ft \\ A=73.5ft^2 \end{gathered}

The length of a rectangular room is 6.5 m in the width is 4.23 meters. What is the perimeter of the room? Report the answer with
LuckyWell [14K]
Perimeter is equal to 2l+2w, or 2 times the length plus 2 times the width. 

So to solve for this you'd take 2(6.5) + 2(4.23). 
2(6.5)= 13
2(4.23)= 8.46

13+8.46= 21.46 meters. 

Based on this, the answer is C.
