Answer:
The answer to your question is ∠3 = 24°
Step-by-step explanation:
Data
∠4 = 11x
∠3 = 4x
Process
1.- From the picture, we know that angles 3 and 4 are complementary so if we sum them up the result is 90°.
∠3 + ∠4 = 90°
2.- Substitution
4x + 11x = 90°
3.- Simplification and result
15x = 90°
x = 90/15
x = 6
4.- Find angle 3
∠3 = 4(6)
∠3 = 24°
Answer:
The tree is 17.5 ft tall
Step-by-step explanation:
We can use ratios to solve
Shadow
-----------
height
28 8
------ = ------------
tree 5
Using cross products
28*5 = 8 * tree
140 = 8 * tree
divide each side by 8
140/8 = 8 *tree/ 8
17.5 = tree
I think this is the answer I hope this helps you
We can use the points given to solve for the slope.
Slope formula: y2-y1/x2-x1
7-3/4-1
4/3
Find the y-intercept.
y = mx + b
3 = 4/3(1) + b
3 = 4/3 + b
5/3 = b
The slope of a perpendicular line is the opposite and reciprocal.
4/3 -> -3/4
Write the new equation.
y = -3/4x + 5/3
Best of Luck!
