Answer:
x=55
a=11.47
Step-by-step explanation:
To find x we add all the angles in the triangle. The three angles in a triangle add to 180 degrees
35+x+90 = 180
Combine like terms
125+x=180
Subtract 125 from each side
125-125+x=180-125
x= 55
To find a
sin 35 = opposite side/ hypotenuse
sin 35 =a/20
Multiply each side by 20
20sin35 =a
11.47152873 =a
Answer:
See below.
Step-by-step explanation:
In all triangles, the three interior angles will add up to 180°. Therefore:
Remember that the little square means a right angle.
Now, solve for <em>x</em>.
Now, plug <em>x </em>back into the equations to find each angle:
