Answer:
m<A = 70 deg
Step-by-step explanation:
The sum of the measures of the angles of a triangle is 180 deg. Add the three measures and set equal to 180. Solve for x. then use the value of x and the expression for m<A to find the measure of angle A.
m<A + m<B + m<C = 180
5x - 25 + 2x + 10 + 3x + 5 = 180
10x - 10 = 180
10x = 190
x = 19
m<A = 5x - 25 = 5(19) - 25 = 95 - 25 = 70
Answer: m<A = 70 deg
Answer:
Option 4 is your answer.
Step-by-step explanation:
Log3 9=2
Explanation:
logo a= n <—> a = b^n
—-> 3^2 = 9 —> log3 9= 2
Answer:
y=x
Step-by-step explanation:
Slope intercept form of a line
y = mx+b
m is the slope
y = 1x+b
Substitute in the point
1 = 1*1+b
1 = 1+b
Subtract 1 from each side
1-1 =1-1+b
0=b
y = 1x
y=x
