Angle PTG = arccos((18^2 + 13^2 - 27^2) / (2 x 18 x 13)) = arccos(-236 / 468) = arccos(-0.5043) = 120 degrees.
The triangle is an obtuse triangle (because one of the angles is greater than 90 degrees) and a scalene triangle (because all the sides are not equal).
60x0.25=15
60x0.10=6
51x0.25=12.75
13.35-12.75
D-6
Q-51
Answer:
B
Step-by-step explanation:
We can easily solve this problem by using the Pythagorean Theorem.
The Pythagorean Theorem says:
One Leg ^ 2 + Another Leg ^ 2 = Hypotenuse ^ 2
<u>Note:</u> This theorem holds true for right triangles
This problem is in fact of a right triangle as said. So we use the theorem to find the other leg's length.
One Leg ^ 2 + Another Leg ^ 2 = Hypotenuse ^ 2
8^2 + Another Leg ^ 2 = 17^2
64 + Another Leg ^ 2 = 289
Another Leg ^ 2 = 289 - 64
Another Leg ^ 2 = 225
The other is the square root of 225, which is 15
The correct answer is B
Answer:
y=0
Step-by-step explanation:
So you would do -4(6y-3) and divide that by -4
then you would do 12 and divide that by -4
or
You could do
-6y-3 which equals -3
then
add three to both sides like this -6y-3+3=-3+3
then simplify it to -6y=0
then divide -6y over -6 and 0 over -6
then it will simplify to 0
Answer:
B) One solution
Step-by-step explanation:
Clearly, the two linear equations graphed have one point of intersection, which means one solution.
