Answer: The length of the base is 10.
Step-by-step explanation:
You can draw an isosceles triangle like the one shown attached.
An isosceles triangle has two equal sides. Then, you can divide it into two right triangles, where the base of each one of them will be:
The hypotenuse of each right triangle shown is 13 and the other legs are (x+7) and x, therefore you can apply the Pythagorean Theorem:
Simplify the expression:
Use the quadratic formula, where:
Then:
Choose the positive value, because lengths are not negative.
Substitute the value of x into the base 2x. Therefore, the answer is:
Answer:
7,2
Step-by-step explanation:
Answer:
The flag pole is 38.96 feet tall.
Step-by-step explanation:
The angle of depression from the top of the flagpole to an object on the ground is 33°.
The object is 60 feet from the base of the cliff.
We need to find the height of the flag pole.
Here, base, B = 60 feet
We know that,
Put all the values to find P.
So, the flag pole is 38.96 feet tall.
4^3 = 64 so log_4(64) = 3 giving y = 3
Answer:
Both -6x +7>-5 and 14x-2<12
Step-by-step explanation:
Your question said "Which of the FOLLOWING inequalities require the inequality symbol to be reversed when solving" I hope this means multiple choice because i got both 14x-2<12 and -6x +7>-5 to be reversed when i finished solving them. For 6x +7>-5 I got X < 2, and for 14x-2<12 I got X > -28, therefore those two are correct.
