Answer:
Answer A
Step-by-step explanation:
Angle A = 180 - 26 - 90 (90 right angle)
The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
cos
(
A)=
adj/hyp
Cos (26) = a / 13
a = 13* Cos (26)
a= 11.7
Find the last side of the triangle using the Pythagorean theorem.
Lets solve this problem:(5x^2)(5x^2)^2
so first of all you would do the () first
so lets do the first one first. 5x^2 = 5*5 wich would equal 25
so the () by each other means multiply
so now its: 25*(5x^2)^2
5x^2= 5*5=25
now its: 25*25^2
do 25^2 first: 25 * 25 =625
625*25
625*25=15,625
your answer 15,625
Answer:
15625
Your welcome. Have a great day :D
Answer:
contrapositive
Step-by-step explanation:
The <u>converse</u> statement would be ...
b ⇒ a
The <u>contrapositive</u> swaps the parts and negates them both:
¬b ⇒ ¬a . . . . . matches your given statement
The <u>inverse</u> negates both parts:
¬a ⇒ ¬b
A <u>contradiction</u> arises when the implication is false: a is true and b is false.
Answer:
Step-by-step explanation:
Given
Required
Use the expression to prove a trigonometry identity
The given expression is not complete until it is written as:
Going by the Pythagoras theorem, we can assume the following.
- a = Opposite
- b = Adjacent
- r = Hypothenuse
So, we have:
Having said that:
The expression can be further simplified as:
Substitute values for sin and cos
becomes
