Angle 3:
62+47=109
All angles in a triangle add to 180 degrees, so 180-109= 71 degrees
Angle 2:
Angles in a straight line always add to 180 degrees too,
so 180-62= 118 degrees
Angle 1:
Again, angles in a triangle add to 180,
so 180-22-118= 40 degrees
Angle 1: 40
Angle 2: 118
Angle 3: 71
Hope that helps :)
Answer:
There are no like terms hence they stay the same
Step-by-step explanation:
x + (y + 9)
There are no like terms
=x+y+9
(x + y) + 9
There are no like terms
=x+y+9
<u>Answer:</u>
The correct answer options are A, B, C and D.
<u>Step-by-step explanation:</u>
A. Leg-angle (LA):
According to this theorem, if the leg and an acute angle of one right triangle are congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.
B. Hypotenuse-leg (HL):
If any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.
C. Hypotenuse-angle (HA):
If the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.
D. Leg-leg (LL):
If any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.
The answer is D
x-2y = 10
