Answer:
<h3>x = 49.6°</h3>
Step-by-step explanation:
Find the image attached;
From the image;
opposite side = 16
Hypotenuse = 21
Angle of inclination = x
Using the SOH identity
sinx = opposite/hypotenuse
sin x = 16/21
sin x = 0.7619
x = arcsin 0.7619
x = 49.6° (to the nearest tenth of a degree)
Answer:7 and 3/16
Step-by-step explanation: 2+1+3=6. 3/4 + 1/8 +5/16 = 1 and 3/16. 6 + 1 and 3/ 16= 7 and 3/16
X= 30
Y=28
Step-by-step explanation:
It's a right-angle triangle. So, 3 x 30 will give you a 90 degree angle.
180-90=90
That means the next 2 angles should add to 90.
2x28=56
56+34=90
Hope this helps!
