Angle QRT is an exterior angle to the triangle. The rule is that the exterior angle of a triangle is equal to the sum of its remote interior angles. Those remote interior angles are angle RTS and angle TSR. So our equation is
. We can remove the parenthesis and simplify by combining like terms to get 9x = 5x + 9 + x and 9x = 6x + 9 and 3x = 9. That means that x = 3.
Answer:
0.64s
Step-by-step explanation:
Hello!
To solve this problem we must use the equation to determine for what time (t), the ball touches the ground that is when h = 0
Now we have a quadratic equation, which has two answers, for this we use the following equation
a = number that accompanies the variable t ^ 2
=-16
b = number that accompanies the variable t
=4
c = independent number of t=4
solving
remember that when the equation is quadratic it has two answers, one with the sign (+), and another with the sign (-), you choose the positive result since it is impossible for the time to be negative
t1=0.64s
t2=-0.39s
answer=0.64s
Answer:
150
Step-by-step explanation:
you get the area of one of the sides that is a triangle.
you multiply that by the length.
so for this question it's
(1/2)(5*6)=15
15*10=150
