Answer: d)
Step-by-step explanation:
7 is the opposite
25 is the hypotenuse
24 is the adjacent
if u refer back to SOH CAH TOA
cos = adj divided by the hyp
cos K = 24/25
*please make sure to double check for yourself or get another person to look it over just incase*
Answer:
Option C.
Step-by-step explanation:
Given information: In triangle ABC, ST║AC, SB=10 ft, BT=9 ft and CT=2.7 ft.
Triangle proportionality theorem: If a line segment parallel to a side of a triangle then the line segments divides the remaining sides proportionally.
Using triangle proportionality theorem we get


On cross multiplication we get


Divide both sides by 9.

The length of SA is 3ft.
Therefore, the correct option is C.
Your equation: 4x² - 100 = 0
Factor the left side: (2x + 10) · (2x - 10) = 0
This equation is true if either factor is zero.
-- One factor: 2x + 10 = 0
Divide each side by 2: x + 5 = 0
Subtract 5 from each side: x = -5 .
-- The other factor: 2x - 10 = 0
Divide each side by 2: x + 5 = 0
Add 5 to each side: x = 5 .
B. If Karl runs 1 mi, then he runs 5280 ft.
If A then B and if B then C, then A-->C
