The Standard Form equation of a line has the following formula: <span><span>Ax+By=C, where </span><span>A≠<span>0 and B</span></span></span>≠0 ;
In your case, 3x + (-7)y = 9 ;
7. the wall is 12 the ladder is 15 find the ground
this will make a right angle from the wall and the ground
a^2+b^2=c^2
12^2+b^2=15^2
144+b^2=225
-144 both sides
b^2=81
square root both sides
b=9 ft
8. area of square is s^2
s^2=81
square root both sides s=9cm
diagonal=
a^2+b^2=c^2
9^2+9^2=c^2
81+81=c^2
162=c^2
square root both sides
12.73cm is diagonal
9. a^2+b^2=c^2
a=9
b=12
c=
9^2+12^2=c^2
81+144=c^2
225=c^2
square root both sides
c=15km
Answer:
Circle = 7
Pentagon = 8
Square = 12
Square + Square + Square = 36
Step-by-step explanation:
Since you know the circle is 7, the square plus the pentagon must be 20. That means the pentagon in the third equation is 8. This means the square is 12.
So, 12 + 12 + 12 = 36.
Answer:
∠c' and ∠c'' are complementary angles
Step-by-step explanation:
Since form a straight angle, then
then they are supplementary angles.
Since the is perpendicular and bisects ∠C
∠c' and ∠c'' are complementary angles
