Answer:
the answer is
x + y + z = 180 degrees
proof
the sum of all angles in the triangles is always equal to 180 degrees
Step-by-step explanation:
Answer: 30 students
Step-by-step explanation:
Ezpeezee:
Since we know the two angle measures equals 145...
(4x+5)+(6x-10)=145
Combine like terms and you get...
10x-5=145
Solve for x...
Add 5 on both sides and you get 150. Then divide by 10 and you get 15.
However, we arent finished yet... We still need to find XMN. The equation for m<XMN= 6x-10. PLUG 15 IN FOR X...
90-10
and that simplifies to 80 degrees.
Any questions?
Answer:
Step-by-step explanation:
Add 4 to both sides:
Subtract 2x from both sides:
Divide both sides by -1:
Answer:
you can turn this division problem into a multiplication problem by multiplying the top fraction by the reciprocal of the bottom fraction.
