So if the exterior angle is 130°, then the inner angle is 50°.
The total of the inner angles of a triangle is (n-2)180°=180°, so 180°-50°=130°
With the remaining two angles =130° and they are both in the ratio of 2:3, one angle has a measure of 52° and 78°.
Thus the measure of the largest angle is 78°.
Answer: -9
Step-by-step explanation: 2 + 7 = 9 and just put an negative in front of 9

Answer:
15.65
Step-by-step explanation:
a^2+b^2=c^2
7^2+14^2=c^2
add 49+196=245
245=c^2
square root everything to get 15.65
10 and 40. 40 is 4 times 10, and 10 + 40 = 50
Ok here's what I make of this: you're in calculus and you're working with functions and their first derivatives, which are the position function and the velocity function, respectively. You need to figure out what the functions are so you can solve the problem. But the acceleration due to gravity goes into the velocity function as -32t; in the position function, the antiderivative of velocity, it goes in as -16t^2. The position function is s(t) = -16t^2 + 48t + 400. When you solve that for t, what you get is the time the rock hits the ground. When you find that t value, sub it into the velocity equation to find the velocity at that time the rock hits the ground. Solving for t (using the quadratic equation) you get a t value of 6.720153. The velocity equation, the first derivative, is v(t) = -32t + 48. Subbing the t value of 6.720153 in you get that the velocity is -167.045. Negative is correct here as well because it was positive going up and now it's coming down.
