1.
a^2+b^2=c^2
easy
a=a
b=13
c=21
a^2+13^2=21^2
a^2+169=441
minus 169 both sides
a^2=272
sqrt both sides
a=16.4924
D is answer
2. same thing
a=18
b=26
18^2+26^2=c^2
324+676=c^2
1000=c^2
sqrt both sides
31.6228=c
C is answer
3.
one way is to plug them in
remember that hypotonuse is longest side
A. 7^2+24^2=25^2, is that true?, yes it is treu
answer is A
4.
legs are 6 and 4
a=6
b=4
c=x
4^2+6^2=x^2
16+36=x^2
52=x^2
sqrt both sides
7.2111=x
7.2=x
5.c=20
a=x
b=14
x^2+14^2=20^2
x^2+196=400
minus 196 both sides
x^2=204
sqrt both sides
x=14.2829
x=14.3

45 dogs and 52 cats because 5+7=12 so 45+7=52
Answer:
y = -1
Step-by-step explanation:
When solving this equation use the distributive property and get...
-4 (y - 2) = 12
-4y + 8 = 12
-4y = 12 - 8
-4y = 4
y = -1
Answer:
37
Step-by-step explanation:
Right Scalene Triangle
Side a = 37
Side b = 12
Side c = 35
Angle ∠A = 90° = 1.5708 rad = π/2
Angle ∠B = 18.925° = 18°55'29" = 0.3303 rad
Angle ∠C = 71.075° = 71°4'31" = 1.2405 rad
C=71.075°B=18.925°A=90°b=12a=37c=35
Area = 210
Perimeter p = 84
Semiperimeter s = 42
Height ha = 11.35135
Height hb = 35
Height hc = 12
Median ma = 18.5
Median mb = 35.51056
Median mc = 21.2191
Inradius r = 5
Circumradius R = 18.5
