Answer:

Step-by-step explanation:
<u>Right Triangles</u>
Right triangles are those who have a right angle, i.e. 90°. The other two angles must sum 90° to complete the 180° which must sum the internal angles of a triangle.
The image shows a circle with two similar triangles FAD and EAD. We know they are congruent because they share the same height and have a base of the same value (as indicated by the ticks). The segment AD must be perpendicular to FE since it comes from the center of the circle. We can conclude
is right, i.e. measures 90°.
We know
, so the required angle
must be 90°-48°=42°.

So first, we need to find a common denominator, make the numbers below the line equal to each other
to do this, we multiply the denominator AND numerator of 4/10 so you can get the equivilent fraction with a denominator of 100
4*10=40
10*10=100
4/10=40/100
now we add the two fractions together and we get
38/100+40/100=
78/100 of a meter
I’m pretty sure it’s the last one
