Answer:Answer:
13.0feet
Step-by-step explanation:
Given ΔDEF with ∠F=90°, the measure of ∠D=19°, and DE = 40 feet, since one of the angles of the triangle is 90°, the triangle is a right angled triangle as shown in the attachment.
Using SOH, CAH, TOA to get the unknown EF.
Since <D is opposite to side EF, EF will be the opposite while side DE will be the hypotenuse
Based on SOH:
Sin<D = Opposite/Hypotenuse
Sin<D = EF/DE
Sin19° = EF/40
EF = 40sin19°
EF = 13.0 feet to the nearest tenth of a foot
A. D and E are similar but not congruent.
Answer:
322 feet
Step-by-step explanation:
first lets plug in our value for s in the equation
.05(70)^2+ 1.1(70)
we then sqaure 70 to get
.05(4900) + 1.1(70)
Then multiply to get
245 + 77
then add to get
322 feet
