Answer:
35° (I may be wrong)
Step-by-step explanation:
An isosceles triangle has an interior angle sum of 180° (like all triangles).
So...
180°-40°= 140°
And because we know that isoceles triangles and two congruent sides, we just have to divide 140° by 2.
140°÷2=70°
But the picture says 2h and h is a side so...
70°÷2=35°

Answer: Choice C</h3>
Work Shown:
So that's why the answer is choice C
The requirement that x is nonzero isn't technically necessary. The original expression simplifies to choice C even when x = 0 is the case. Also, we don't have issues such as division by zero errors that could arise. It's a bit curious why your teacher put in that condition.
Answer:
I think it is C sorry if it wrong
Step-by-step explanation:
Answer:155 hours
Step-by-step explanation:
$75+$6h=$1,000
Subtract $75 on both sides:
$75-$75+$6h=$1,000
$6h=$925
Divide 6 on both sides:
6/6h=925/6
h=154.1666667
After I rounded it and it was 155 hours
Answer:
Step-by-step explanation:
Let the height of the largest triangle marked be 
. We can set up the following equation:
(if you're unfamiliar with trig, this is likely introduced to you as 30-60-90 triangle rules)
This height is also a leg of a 45-45-90 triangle, as marked in the diagram. From the isosceles-base-theorem, the other leg of this triangle must also be equal to . Therefore, we can use the Pythagorean theorem to solve for 
:
(you can also use trig or 45-45-90 triangle rules which are derived from the Pythagorean theorem)
Segment 
consists of two shorter segments, a left segment and a right segment. We've already found that the left segment is equal to 17. To find the right segment we can use trig, the Pythagorean theorem, or 30-60-90 triangle rules (derived from the Pythagorean theorem):
Using Pythagorean Theorem:
Therefore, we have:
