To find out the missing leg of a right triangle, you have to use the Pythagorean Theorem which is a^2 + b^2 = c^2. C is the hypotenuse. So, substitute the numbers into that equation.
2^2 + 4^2 = x
4 + 16 = x
20 =
If I assume that p is supposed to be r, then:
r = 12.5
or
r = 25/2 is improper or 12 & 1/2 is proper
Answer:
1. x/2=1.75/3.5 x=1
2. 4/2=y/3.5 y=3.5
3. P (Figure Left)=3+5+2+1+4+8+3+2=28 cm
A (Figure Left)=8x2-2x1-3x2=8 cm2
4. P (Figure Left) / P (Figure Right) = 1/1.75 = 28/ P (Figure Right)
P (Figure Right)= 49 cm
A (Figure Left) / A (Figure Right) = 1/1.752 = 8/ A (Figure Right)
A(Figure Right)= 24.5 cm2
Step-by-step explanation:
1. x/2=1.75/3.5 x=1
2. 4/2=y/3.5 y=3.5
3. P (Figure Left)=3+5+2+1+4+8+3+2=28 cm
A (Figure Left)=8x2-2x1-3x2=8 cm2
4. P (Figure Left) / P (Figure Right) = 1/1.75 = 28/ P (Figure Right)
P (Figure Right)= 49 cm
A (Figure Left) / A (Figure Right) = 1/1.752 = 8/ A (Figure Right)
A(Figure Right)= 24.5 cm2
Answer:
19
Step-by-step explanation:
1st you will use a^2+b^2=c^2
next you plug them in so it would be a^2+16^2=25^2
next you would solve it to a^2+256=625
then you would get 369 and square root it
and your answer will be 19.2.
