What is the measure of _M?
grandymaker [24]

Answer: I think I cn help bt nt sure

Step-by-step explanation:

X° + 52° + 78° = 180°

X° + 130° = 180°

X° + 130° - 130° = 180° - 130 °

X° = 50°

M is <50°

7. In the accompanying diagram of rhombus CDEF, diagonal FD is drawn and the
tatiyna

Answer:

m∠CFD is 70°

Step-by-step explanation:

In the rhombus

  • Diagonals bisect the vertex angles
  • Every two adjacent angles are supplementary (their sum 180°)

Let us solve the question

∵ CDEF is a rhombus

∵ ∠E and ∠F are adjacent angles

→ By using the second property above

∴ ∠E and ∠F are supplementary

∵ The sum of the measures of the supplementary angles is 180°

∴ m∠E + m∠F = 180°

∵ m∠E = 40°

∴ 40° + m∠F = 180°

→ Subtract 40 from both sides

∵ 40 - 40 + m∠F = 180 - 40

∴ m∠F = 140°

∵ FD is a diagonal of the rhombus

→ By using the first property above

∴ FD bisects ∠F

→ That means FD divides ∠F into 2 equal angles

∴ m∠CFD = m∠EFD = \frac{1}{2} m∠F

∴ m∠CFD = \frac{1}{2} (140°)

∴ m∠CFD = 70°

Can Someone Please Help Me With This Question. I'll post a picture of the question ​
Vedmedyk [2.9K]

Answer:

y-7=3(x-9)

Step-by-step explanation:

The form of equation of line given in the problem is the point-slope form of a line. That is given by:

y-y_1=m(x-x_1)

We need y_1 and m (denoted by boxes)

y_1 is the y coordinate of the first set of points.

The first coordinate pair is (9,7), so y_1  would be 7

y_1=7

Now, the slope (m).

It has formula

m=\frac{y_2-y_1}{x_2-x_1}

So, x_1 = 9

y_1 = 7

x_2 = 4

y_2 = -8

Substituting, we get the slope to be:

m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{-8-7}{4-9}\\m=\frac{-15}{-5}\\m=3

Hence, the equation of the line in point-slope is:

y-7=3(x-9)
