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\°

In ∆MNP, m∠N = 90º, NH – altitude, m∠P = 21º, PM = 4 cm. Find MH.
Sveta_85 [38]

Answer:

0.51 cm

Step-by-step explanation:

In right triangle MNP, MP = 4 cm, m∠N = 90°, m∠P = 21°

By the sine definition,

\sin \angle P=\dfrac{\text{Opposite leg}}{\text{Hypotenuse}}=\dfrac{MN}{MP}\\ \\MN=MP\sin \angle P\\ \\MN=4\sin 21^{\circ}\approx 1.43\ cm

Now, consider right triangle HMN (it is right because NH is an altitude). By the cosine definition,

\cos \angle M=\dfrac{\text{Adjacent leg}}{\text{Hypotenuse}}=\dfrac{MH}{MN}\\ \\MH=MN\cos \angle M

In the right triangle, two acute angles are always complementary, so

m\angle M=90^{\circ}-m\angle P=90^{\circ}-21^{\circ}=69^{\circ}

Thus,

MH=1.43\cos 69^{\circ}\approx 0.51\ cm

Svetlanka [38]

Answer:

- 5(x - 4) = 30

- 5x + 20 = 30

- 5x = 30 - 20 = 10

x = 10  \div - 5

x =  - 2
