With these equations what you do to one side you have to do to the other and if you divide using a negative such as when you divide -8 you switch the greater than sign to the opposite direction so add 36 and it will cancel and add it to negative 12 which will actually be subtracting because 12 is negative and then you divide negative 8 by both sides

Answer:

1.98

Step-by-step explanation:

In this problem, we are:

Given: ∠D = 26°, Hypotenuse (DF) = 4.5

To solve: EF

Now through the given, we are to focus on point D to solve for EF.

We need to find the relationship of point D to DF and EF.

The relationship here is sine.

Reason: $\frac{opposite}{hypotenuse}$

Through point D, DF is the hypotenuse and EF is the opposite side.

So let's solve this simply through algebra,

sin = $\frac{opposite}{hypotenuse}$

sin(26°) = $\frac{EF}{4.5}$

0.44 = $\frac{EF}{4.5}$

0.44 × 4.5 = EF

1.98 = EF

Triangle DEF is an isosceles, so DEF = DFE.

Katarina [22]

Answer:

m∠CFD= $105\°$

Step-by-step explanation:

we know that

m∠CFD+m∠DFE= $180\°$ ------> by supplementary angles

we have

that

m∠DFE=m∠DEF= $75\°$

so

m∠CFD+ $75\°=180\°$

m∠CFD= $180\°-75\°=105\°$

What is the measure of ABC?

leva [86]

Answer:

B

Step-by-step explanation:

the measure of the chord- chord angle ABC is half the sum of the arcs intercepted by the angle and its vertical angle , that is

∠ ABC = $\frac{1}{2}$ (AC + DE) = $\frac{1}{2}$ (75 + 45)° = $\frac{1}{2}$ × 120° = 60°
