Answer:
x=2
Step-by-step explanation:
Since they are both equal to y set them equal to each other: 2x-3=-8x+17
Subtract 17 from both sides: 2x-20=-8x
Subtract 2x from both sides: -20=-10x
Divide both sides by -10: 2=x
Answer:
128.67 feet
Step-by-step explanation:
We would be solving this question using the Trigonometric function of tan.
Tan( of the angle of elevation) = height of the tower ÷ height of the shadow.
Angle of elevation = 65°
Height of the tower = unknown, which is designated as X
Height of the shadow = 60 feet.
Therefore,
tan 65° = X/ 60 feet
We crossmultiply
X = tan 65° × 60 feet
X = 128.67041523 feet.
Approximately, X = 128.67 feet.
Therefore, the tower is 128.67 feet tall.
2(x-10)exponent2 is the answer
Answer:
3km=3000m
Step-by-step explanation:
if 1 km=1000m,
3 km: 3 x 1000 = 3000m
