Because both sides are given as 10, the two bottom inside angles would be the same.
Since one of the bottom angles is given as 74 degrees, the other bottom angle is also 74 degrees.
The total of those two angles is : 74 +74 = 148 degrees.
The total of the 3 inside angles of a triangle is 180 degrees.
The top angle (B) is 180 - 148 = 32 degrees.
The answer is B.
Answer:
( -4, -3 )
Step-by-step explanation:
Let's solve by elimination. Reason being there are no variables without coefficients.
−5y+3x=3 Multiply equation by 3. Each term.
−8y+9x=−12
-15y + 9x = 9 Subtract the to equations
-8y + 9x = -12
___________
-7y = 21
y = -3
Substitute y into original equation
-5(-3) + 3x = 3
15 + 3x = 3 Subtract 15 both sides
3x = -12 Divide by 3, both sides
x = -4
Answer:
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
