The angles of the triangle are 39°, 51°, and 90°.
Step-by-step explanation:
Step 1:
The sum of all the angles in any triangle is equal to 180°.
We have two of the three angles in terms of x while the third angle is not given directly. Since it is a right-angled triangle, one of the angles equals 90°.
So the angles of the triangle are 
and 
Step 2:
Now, we substitute all the angles to a sum of 180 to determine the value of x.
So x = 13°. The angles are
The angles of the triangle are 39°, 51°, and 90°.
Answer:310
Step-by-step explanation:
l=-1+3w
l=3w-1
l*w=310
(3w-1)*w=310
3w^2-w-310=0
w= 31/3
w= 10 1/3
l=31/3*3-1
l=30
30*31/3=10*31=310
Answer:
angle c = 107°
angle b = 107°
angle a = 73°
Step-by-step explanation:
Given:
Two line XY and WZ intersect each other and make four angle [a, b, c, d]
Given that Angle d = 73°
Find:
angle a
angle b
angle c
Computation:
We know that angle c and angle d situated on same line XY
So,
angle c + angle d = 180°
angle c + 73° = 180°
angle c = 107°
We know that angle b and angle d situated on same line WZ
So,
angle b + angle d = 180°
angle b + 73° = 180°
angle b = 107°
angle a and angle d are vertical opposite angle
So,
angle a = angle d
angle a = 73°
