Answer:
C. 50 degrees
Step-by-step explanation:
Angle EDG is 90 degrees
x = 10
5 multiplied by 10 is 50
4 multiplied by 10 is 40
40+50=90
Answer:
u use cosine
and then some proportion
i am 60% sure
dont trust me
i learned this a week ago and now i forget it all help me study for the quiz i have on this tmrw?
Answer:
confusion?
Step-by-step explanation:
your welcome
Because the triangle is an equilateral triangle, you know that all of the angles are equal to 60°. That means that you can use trigonometry to find the height, which would be sin(60) × 20 = 17.32.
Again, because it is an equilateral triangle, all sides are equal as well, meaning that the base is also 20cm. To find the area of the triangle, we must do (20 × 17.32)/2 = 173.2cm^2, which is the area.
I hope this helps!
Answer:
m∠A= 110°
Step-by-step explanation:
∠A+∠B=180°
5x+20+9x-92=180°
14x=180+92-20
14x/14=252/14
x=18
m∠A=5x+20
= 5(18)+20
=90+20
m∠A=110
