9514 1404 393
Answer:
7) 57.8
8) 73.8
Step-by-step explanation:
The tangents from a given point are the same length. This means the perimeter can be calculated as twice the length of one side plus twice the length of an opposite tangent.
7) P = 2(22.2 +6.7) = 57.8
8) P = 2(22.9 +14) = 73.8

Answer:
THE CORRECT ANSWER IS B- 73 FEETThe given condition in question will form a right angle triangle
and the length of sides of triangle are given 55ft, 48ft and missing one.
Now using pythagoras theorem,55²+48²= x²
x² = 3025 + 2304
x² = 5329
Taking square root of 5329 will give 73 ft!

Answer:
(a) x=45°
(b) If AD was parallel to BC, <A would be equal to (180-<B)=90 (corresponding angles). Since <A≠90, we can see that AD and BC aren't parallel.
Step-by-step explanation:
(a)
Angles in a quadrilateral add to 360:
<A+<B+<C+<D=360
2x+90+x+3x=360
6x=270
x=45°
(b)
If AD was parallel to BC, <A would be equal to (180-<B)=90 (corresponding angles). Since <A≠90, we can see that AD and BC aren't parallel.
Answer: Step-by-step explanation:
3x+2x+x=360-90
6x=270
x=45
∠DAB=2x=90° and ∠ABC=90° ⇒ AD║BC

The right triangle has a perimeter of 40 centimeters.help pls
Answer:
C
Step-by-step explanation:
P= side 1+ side 2 + side 3
40-(17+8)=15
15x8/2=60
Area of triangle, who has perimeter of 40 centimeters is 60 cm².
What is Area of Triangle?Area of a Triangle = A = ½ (b × h) square units
where b and h are the base and height of the triangle, respectively.
Given: Perimeter= 40cm
Now, 17+8+side=40
side= 40-25
side= 15 cm
Now, Area of triangle,
=1/2*b*h
= 0.5*15*8
= 60 cm²
Hence, Area of triangle= 60 cm².
