Answer:
supplementary angle = 60 , complementary angle : none
Answer:
Step-by-step explanation:
Tan Ф = opposite/adjacent = 170/90 = 1.89
Ф = tan⁻¹ 1.89 = 62.1°
tan Ф = x/207
tan 62.1° x 207 = x
1.89 x 207 = 391.23
Answer:
A = 30
Step-by-step explanation:
The area of a triangle is 
Plug in the values given:
A = 1/2 (10) (6) = 1/2 (60) = 30
Answer:
The solution set would be all real numbers
Step-by-step explanation:
Remember that you should pass from one side to the other the terms which are similar, that is to say x with x and numbers with numbers. In doing so you must be sure to change the sign of the term if it is passed from one side to the other.
In this case it would be:
4x + 7x + 1 < 11x + 2
(Four plus seven is 11)
11x + 1 < 11x + 2
We can see that x is eliminated, because we change the sign on 11 to be -11:
11x - 11x + 1 < 2
1 < 2
This result means that no matter which value we give to x, the inequality will be always true. For that reason the answer is all real numbers
