Answer:
Step-by-step explanation:
we have
Solve for m
That means -----> isolate the variable m
Subtract b both sides
Divide by x both sides
Rewrite
<span>All the angles of a triangle add up to 180 degrees.
Since two of the angles are the same, we can write:
2A+B=180
Where 2A accounts for the two angles that are the same.
We are given the relation:
B=A+30
We can plug this into our first equation:
2A+A+30=180
</span><span>
Combine like terms and move the 30 to the other side:
3A=150
Divide both sides by 3:
A=50
We can solve for B by plugging A back into our relation:
B=50+30
B=80
To check: 80+50+50 so we are correct.</span>
Answer:
Area = 77.1
Step-by-step explanation:
The are of a right triangle is
our base and height are 6 for both triangles, so we shall find the area of one of the triangles...
multiply this by 2
Now find the area of the whole circle
our radius is 6, therefore:
Finally, subtract the area of the two triangles from the total are of the circle. The difference left over is our answer
Forty nine x plus 15x -ggsg and y will get 13
