Answer:
what
Step-by-step explanation:
I do not have an answer but you could always take an explanations how to do it easier. Hope it helps :)
Step-by-step explanation:
Example: solve √(2x+9) − 5 = 0
isolate the square root:
√(2x+9) = 5
square both sides:
2x+9 = 25
Now it should be easier to solve!
Move 9 to right:
2x = 25 − 9 = 16
Divide by 2:
x = 16/2 = 8
Answer:
x = 8
Check: √(2·8+9) − 5 = √(25) − 5 = 5 − 5 = 0
This problem is accompanied by a figure.
You can infere these relationships from the figure
(x-5)° = 74° => x = 74 + 5 = 79°
(x-5)° + 58° + (y-1)° = 180 ° => 74 + 58 + y-1 = 180 =>
y = 180 + 1 - 58 - 74 = 47°
Answer: x = 79°, y = 47°. This is the option d)
Answer:
A) 5 units
Step-by-step explanation:
ABC is a 30-69-90 degree triangle whose sides, respectively, are in the ratio of 1 : : 2
so if the hypotenuse is 10, the side opposite the 30° angle is half of that, or 5
Answer:
pretty sure it's D
