How many triangles exist with the given angle measures? 45 45 90
WARRIOR [948]

Answer:

Infinitely many

Step-by-step explanation:

for example,

a triangle of 1 - 1 - \sqrt{2} is  45 - 45 - 90 based on the 45-45-90 triangle theorem

if I multiply the three side lengths listed above by the same number, I will still have a 45 -45 -90 because of the definition of similar triangles

Please help pls pls help pls belp
Delvig [45]

Answer:

After 1 second, the ball will reach a maximum height of 16 feet

Step-by-step explanation:

The height of the ball after t seconds: h(t) = -16t^2 + 32t

The graph of this quadratic function is parabola which opens downwards. The vertex of a quadratic equation is the maximum or minimum point on the equation's parabola

t = -b/2a = -(32)/2(-16) = -32/-32 = 1 second

then

h(t) = -16(1)^2 + 32(1) = -16 + 32 = 16

After 1 second, the ball will reach a maximum height of 16 feet

What is the measure of angle x?<br><br> 10 <br> 15<br> 45<br> 60
EastWind [94]

Answer:

x = 45

Step-by-step explanation:

We know that the sum of (x+30)  and 75 are vertical angles  so they are equal

x+30 = 75

Subtract 30 from each side

x+30-30 = 75 -30

x = 45
