Solve the formula A=10+ry. solve for y
noname [10]

The given formula A= 10 + ry

Solve for y means we have to make y alone

A= 10 + ry \\

Add -10 on both sides, we get

A - 10 = 10 -10 + ry \\A - 10 = 0 + ryA - 10 = ry

As there is multiplication sign between r and y so to solve for y, divide both side by r

\frac{A - 10}{r} = y\\\\y = \frac{A - 10}{r}

In triangle abc, the angle c is six times as large as angle
mote1985 [20]
The interior angles of a triangle add up to 180 degrees

a = 1st angle, b = 2nd angle, c = 3rd angle

c = 6a
b = a + 60
a + b + c = 180

a + (a + 60) + (6a) = 180
8a + 60 = 180
8a = 180 - 60
8a = 120
a = 120/8
a = 15 <=== here is one angle

b = a + 60
b = 15 + 60
b = 75 <=== and another one

c = 6a
c = 6(15)
c = 90 <=== and the last angle
