Answer:
58.666666666667 MMT
Step-by-step explanation:
4% / 6MMT * 88%= 58.6666667MMT
Answer: (-4, -1)
Step-by-step explanation: Since these lines are already graphed, we are looking for their point of intersection. This point where the two lines intersect will represent the x and y that is the solution to this system of equations.
The two lines intersect in quadrant III
where x and y are both negative.
When finding the coordinates of a given point,
be very careful with your signs.
Let's just do a quick review on the coordinate system. On the x-axis, left means negative and right means positive and on the y-axis, down means negative and up means positive.
So to find the coordinates for this point, we start at the origin.
Then we move to the left 4 and down 1 so that's (-4, -1).
So the solution to this system is (-4, -1).
m∠Z = 55°
Solution:
Given m∠A = 75° and m∠B = 50°
Let us first find the m∠C.
Sum of the angles of the triangle is 180°.
In ΔABC,
m∠A + m∠B + m∠C = 180°
⇒ 75° + 50° + m∠C = 180°
⇒ 125° + m∠C = 180°
⇒ m∠C = 180° – 125°
⇒ m∠C = 55°
Given ΔABC ≅ ΔXYZ.
Corresponding parts of congruence triangles are congruent.
⇒ m∠Z = m∠C
⇒ m∠Z = 55°
Hence, m∠Z = 55°.
