Answer:
Step-by-step explanation:
*Notes (clarified by the person who asked this question):
-The triangle on the right has a right angle (angle that appears to be a right angle is a right angle)
-The bottom side of the right triangle is marked with a question mark (?)
<u>Triangle 1 (triangle on left):</u>
Special triangles:
In all 45-45-90 triangles, the ratio of the sides is , where is the hypotenuse of the triangle. Since one of the legs is marked as , the hypotenuse must be
It's also possible to use a variety of trigonometry to solve this problem. Basic trig for right triangles is applicable and may be the simplest:
<u>Triangle 2 (triangle on right):</u>
We can use basic trig for right triangles to set up the following equations:
,
We can verify these answers using the Pythagorean theorem. The Pythagorean theorem states that in all right triangles, the following must be true:
, where is the hypotenuse of the triangle and and are two legs of the triangle.
Verify
I believe the answer is 4. I did an assignment and got it right
9x-3 +(3-5x)=5x-15+(3-5x)
4x=18
x=18/4
x=9/2
Answer:
4 feet squared
Step-by-step explanation:
Hilda's bank balance will remain above $395 fewer than 14 weeks.
The information provided in the question can be modelled into an equation: Required balance = amount she has in her account - (amount by which balance changes x number of weeks)
$395 = $550 - ($82.50t)
We are to determine the value of t. In order to determine the value of t, take the following steps:
Combine similar terms
$82.50t = $1550 - $395
Add similar terms
$82.50t = $1155
Divide both sides of the equation by 82.50
t = 14 weeks
