Triangles have 
in total, so the sum of all the angles should be
First triangle
Second triangle
You multiply 8 and 5 to get 40 then you divide 300 into 40 to get the answer which is 7.5
Step-by-step explanation:
soln:
let,
(x1,y1) =(2,4)
(x2,y2)=2,-7)
Now,
By midpoint formula,
×= <u>x</u><u>1</u><u>+</u><u>x</u><u>2</u>
2
= <u>2</u><u>+</u><u>2</u>
2
=<u>4</u>
2
=2,,
And,
Y=<u>y</u><u>1</u><u>+</u><u>y</u><u>2</u>
2
=<u>4</u><u>-</u><u>7</u>
2
= <u>-</u><u>3</u>
2
Hence ,
The mispoint between points (2,4) and (2,-7) is (2,<u>-</u><u>3</u><u> </u><u> </u><u> </u><u>)</u>

Answer:
<h2><u><em>
x = √95</em></u></h2>
Step-by-step explanation:
from the sign on the picture it is a rigth triangle
we use pythagoras
x² = 12² - 7²
x² = 144 - 49
x² = 95
x = √95
(x = 9.75)
Answer:-1 over 2.
