Answer:
38 degrees
Step-by-step explanation:
this is an isosceles triangle, meaning that the base angles are congruent.
the total triangle is equal to 180
so the equation would be: x=180 - (71+71)
evaluate:
x=180-142
x=38 degrees
Hope this helps :)
Answer:
Step-by-step explanation:
Given
Required
Determine the length of the congruent sides
Since, the triangle is an isosceles triangle, the perimeter would be calculated using
Where P represents Perimeter and B represents Base
So:
Solve for 2L
Divide through by 2
<em>Hence; The length (L) of the congruent sides is </em><em></em>
Answer:how
Step-by-step explanation:what is this it’s too hard I’m sorry man
By SOH CAH TOA, the sine of an angle is its opposite side divided by the hypotenuse.
The opposite of ∠C is 12, the hypotenuse is 20.
sin(C)= 12/20=3/5=0.60
Good luck!
Answer:
a) $8.80
b) 40%
Step-by-step explanation:
<u>Part (a)</u>
Given:
- Original price = $22
- Discounted price = $13.20
Original price - discounted price
= $22 - $13.20
= $8.80
<u>Part (b)</u>
percentage = (amount discounted ÷ original price) x 100
= (8.80 ÷ 22) x 100
= 40%
