Answer: m<1 is 60, m<2 is 60, and m<3 is 120
Step-by-step explanation:
M<1 is 60 and m<2 is also 60 because the interior triangle angles have to equal 180 so M<1 + m<2 + 60 = 180 so m<1 and m<2 are both sixty.
m<3 is 120 because m<2 and m<3 are supplementary so if a supplementary angle is equal to 180 then m<2 + m<3 = 180 and m<2 is 60 so m<3 is 120.
Answer:
Step-by-step explanation:
Consider the quadratic equation, we have

Dividing the equation by a, we get

Put
on the other side,

Add
on both the sides,

completing the square, we have

Now, solving for x,


Multiply right side by
,

which is the required quadratic formula.
Answer:
48
Step-by-step explanation:
If we know that the max possible score is 100%, and she got 80% for getting 60 marks, we can set it up as a porportion.
60 * 80 = 4800
4800/100 = 48
Answer:
59°
Explanation:
If you add the angles 99° from angle C in the top shape and add 22° on the bottom shape it will give you 121°. When you get this subtract it from 180°
180°-121°= 59°
So, it's 58°
You can check by adding 180°+121°+59° = 180°
