Answer:
y=13 degrees
Step-by-step explanation:
This is an isosceles triangle, we know this because NO and NM are equal.
In an isosceles triangle, the base angles are congruent. In this case, they are angle NOM and angle NMO.
We also know that the sum of the interior angles of a triangle are equal to 180.
With this information, we can make an equation by gathering all the interior angles:
8y+2(3y-1)=180
Solve for y.
8y+6y-2=180
14y-2=180
14y=182
y=13
Answer: A
Step-by-step explanation:
The line and dots are closed circle, so B and D would not be the answer.
The line have passed through the point (-6,4) and (0,2); we uses to find the slope.
slope = m = (y2 - y1)/(x2 - x1) = (2 - 4)/(0 - (-6)) = -2 / 6 = -1/3
we plug in slope to the linear equation in form of y = mx + b, where m is the slope, and b is the y- intercept.
y = -1/3x + 2
So the answer is A.
Answer:
(A) looks right

I am sorry if i am wrong
This doesn't make sense, as a triangle much equal 180, so it cannot have two angles bigger than 90, because this would mean it cannot be acute. A right triangle has one angle that is 90, obtuse as one that is bigger than 90 and two that are less, and an acute has three angles less than 90. Maybe there's a typo here?
One way to do it is first taking the g(25) and sub in so g(25)= √25 =5 then sub f(5)= 5 ² - 6(5) = 25-30 = -5
