Answer:
m∠J =90°
m∠O = 140°
Step-by-step explanation:
We see here angle J having 90°, pure right angle shape.
m<J=90
Then we find the total interior angle using (n-2)*180
(4-2)*180
360°
So, m∠O = 360° - m∠J - m∠E -m∠K
m∠O = 360° - 90° - 80° -50°
m∠O = 140°
In system A, the first equation multiply by 4
8x - 4y = 12 (1st)
3x + 4y = 10 (2nd)
--------------------add
11x = 22
So answer is B.
Answer:
x = 24.27385%
Step-by-step explanation:
We can say 96.4x=23.4
Divide by 96.4: (x=23.4/96.4) = 0.24273858921
x=0.24273858921 so x = 24.27385...%
Answer:
Obtuse Triangle
Step-by-step explanation:
When there is an angle with a measurement greater than 90 degrees, the triangle is an obtuse triangle.
