It’s obtuse
Explanation:
Assign the sides by length with c being longest
If (a^2)+(b^2)>(c^2) it’s acute
If (a^2)+(b^2)=(c^2) it’s right
And if (a^2)+(b^2)<(c^2) it’s obtuse
Since (3^2)+(9^2)=9+81=90
And 10^2=100 we know that (a^2)+(b^2)<(c^2) so it’s obtuse
Answer: c is perpendicular to y = -5x - 2
Explanation: The slope of a perpendicular line is an opposite reciprocal of the original slope/line. (Basically switch the numerator and denominator and the sign. In this case, the slope is -5/1x. It’s opposite reciprocal is 1/5x.)
You can take a look at my notes for further clarification. Hope this helps!
Answer:
10
Step-by-step explanation:
because 10 times three is 30 plus 15 equals 45
Answer:
the simple interest is Rs. 30
6/8
This is because tan is opposite over adjacent
6 is opp of A, and 8 is adjacent A
