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
Answer:
B. 175 square cm
Step-by-step explanation:
Area of the figure = Area of parallelogram + Area of square + Area of triangle
Area of parallelogram = (base x height)
= (14 x 5)
= 70 
Area of square = (length x length)
= (7 x 7)
= 49
Area of triangle = (
base x height)
= ( x 16 x 7)
= 56
Area of the figure = 70+ 49 + 56
= 175
The area of the figure is 175 .
Answer:
Yintecept is 0
Step-by-step explanation:
because it's y= Mx+b
but this one is y = mx
Answer:
z=7
Step-by-step explanation:
area = ½ × (a + b) × h.
260 = 37 + 4z × 8 ×0.5
260/0.5 = 520
520/8=65
37 + 4z = 65
65-37 = 28
28/4=7
z=7
37.68m this is my best guess sorry if it's wrong :)
