Answer: \boxed{30^{\circ}, 60^{\circ}, 90^{\circ}}

Step-by-step explanation:

Let the smallest angle be x.

Then, the middle angle is x+30.

The largest angle is 2x+30.

Angles in a triangle add to 180 degrees, so:

x+x+30+2x+30=180\\\\4x+60=180\\\\4x=120\\\\x=30

So, the angles measure \boxed{30^{\circ}, 60^{\circ}, 90^{\circ}}

The formula for velocity of an object is the equals d over t where he is a velocity of the object t is the distance traveled and
butalik [34]

Answer:

(a)\ t =\frac{d}{v}

(b)\ d = vt

Step-by-step explanation:

<em>The question is mixed up with details of another question. See comment for original question</em>

<em />

<u>Given</u>

v = \frac{d}{t}

v \to velocity

d \to distance

t \to time

Solving (a): Solve for time

We have:

v = \frac{d}{t}

Cross multiply

t * v = d

Make t the subject

t =\frac{d}{v}

Solving (b): Solve for distance

We have:

v = \frac{d}{t}

Cross multiply

d = v * t

d = vt

5. Find a counterexample to show that the following con-
Bess [88]

Answer:  see below

<u>Step-by-step explanation:</u>

Any value x such that |x| < 1 will make the conjecture false

<em>In simpler words, let x be a fraction between 0 and 1.</em>

One example: Let x = \dfrac{1}{2}

Then x⁴ = \bigg(\dfrac{1}{2}\bigg)^4

             = \dfrac{1}{16}

\dfrac{1}{16} < \dfrac{1}{2}

so the conjecture is false.
