Answer:
x°+2x°+(x-24)°=180°
Step-by-step explanation:
The sum of of the interior angles of all triangles add up to 180°
Adding x°, 2x°, and (x-24)° <em>will</em> equal 180
Therefore, an equation that can be used to solve for the missing angles is: x°+2x°+(x-24)°=180°
Sin θ = 2 / 7
tan θ > 0
cos θ = ?
sin θ = opposite / hypotenuse
tan θ = opposite / adjacent
cos θ = adjacent / hypotenuse
short leg = opposite = 2
hypotenuse = 7
long leg = adjacent = ?
adjacent = √(7² - 2²)
adjacent = √(49 - 4)
adjacent = √45
adjacent = √9 * 5
adjacent = 3 √5
cos θ = adjacent / hypotenuse
cos θ = 3√5 / 7
The answer is 6.
To do this, remember PEMDAS?
You would first have to add what is in the parenthesis THEN do -3 + 9 to get 6.
Answer:
200 in2
Step-by-step explanation:
diameter= 15 in. so raduis = 15/2
area of circle = πr2
= 22/7 * 15/2 *15/2
= 176.79
rounding to the nearest 100, its 200 in2
Represent as an expression:
32 + 5x
Plug 5 for x and solve:
32 + 5(5)
32+10
42
Solution: B. 42
I hope I helped you with your solution! If you could give me brainliest, I would be very thankful!
