Answer:
Nope
Step-by-step explanation:
To now if a triangle is a right angle, use Pythagoras Theorem,
a^2 + b^2 = c^2
C usually be the longest side of the triangle, C = 17
Then also let a and b be 6 and 13 respectively.
6^2 + 13^2 =205
C^2 = 205
C = sqrt(205) = 14.32
therefore no this is not a right angle triangle
<B+<D = 180
x+148 = 180
x = 32
<A = 2(32) + 1
<A = 64+1
<A = 65
The answer is 4.
The easiest way to determine the value of statements like this is to turn the percentage into a decimal and then multiply.
20% * 20
.20 * 20
4
