Answer:
a = 5
Step-by-step explanation:
a^2 + b^2 = c^2
Substitute
b = 12
c = 13
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a =
a = 5

Answer:
141
Step-by-step explanation:
It is a 7 sided shape
first find the sum of interior angles
7-2 x 180 = 900
so 122 +125 +131 +107+ x-15+x+x+7 = 900
477 +3x =900
3x= 423
x=141

Answer:
Step-by-step explanation:All other quantities of physical objects can be expressed as combinations of these fundamental quantities. For example, density is volume per mass. It can be expressed as a combination of the fundamental quantities mass (M) and length (L), M/(L × L × L) = M/L3. Similarly, area is a function of length, L × L = L2.
