Answer:
b = 24 meter
Step-by-step explanation:
Using Pythagoras theorem:
a² + b² = c²
Here given: a = 10 m, b = ?, c = 26 m
<u>Insert values</u>
10² + b² = 26²
b² = 26² - 10²
b² = 676 - 100
b² = 576
b = √576
b = 24

Step-by-step explanation:
What number should the equation x + y = 17 be multiplied by to eliminate y?
Answer:
The answer to your question is x = 3; y = 3
Step-by-step explanation:
Data
angle = 45°
Opposite side = x
Adjacent side = y
hypotenuse = 3√2
To solve this problem, use trigonometric functions.
1) To find x, use the trigonometric function sine.
sin Ф = Opposite side / hypotenuse
-Solve for Opposite side (x)
Opposite side = hypotenuse x sin Ф
-Substitution
Opposite side = 3√2 sin 45
-Simplification
Opposite side = 3√2 (1 / √2)
Opposite side = 3(1)
-Result
x = 3
2) To find y use the trigonometric function cosine
cos Ф = Adjacent side / hypotenuse
-Solve for Adjacent side
Adjacent side = hypotenuse x cos Ф
-Substitution
Adjacent side = 3√2 x cos 45
-Simplification
Adjacent side = 3√2 x (1/√2)
Adjacent side = 3(1)
-Result
y = 3
