multiply 40 by 3/4
40 x 3/4 = 40*3 = 120, 120/4 = 30
he answered 30 correctly
40-30 = 10, he missed 10
The missing steps are each right angles and
.
Solution:
Step 1: Given data:



Step 2: In the two polygons,
and 
(Each right angle)
Step 3: Given

Step 4: By third angle theorem,
If two angles in one triangle are congruent to the two angles in the other triangle, then the third angles in the triangles also congruent.

Step 5: By the definition of congruent polygons,
If two same shape polygons have all the angles are congruent and all the corresponding sides are congruent then the polygons are congruent.
Hence
.
Therefore the missing steps are each right angles and
.
Answer:
b(a+c) this is answer okay
0.0625x = 6
x = 6/0.0625
x = 96
6 is 6.25% of 96
If you want to convert a fraction to a decimal, divide the top by the bottom. Fractions are basically glorified division.
1/2 = 0.5
And you can convert this to a percent by moving the decimal two places to the right. And change it to a % sign.
0.5 => 50%
