WILL REWARD BRAINLESS Acute triangles are similar. Always Sometimes Never

Mathematics
1 answer:
Mkey [24]3 years ago
3 0

Answer: Sometimes.

Step-by-step explanation:

Acute triangles are triangles that have three acute angles (<90 degrees).

For instance, a triangle with angle measures of 45, 50, and 85 would be an acute triangle, as would a triangle with angle measures of 65, 55, and 60. Those two triangles would not be similar, as their side lengths and angles are different. However, a triangle with identical angle measures and different side lengths are similar, whether acute or obtuse.

Can someone help thanks
MAXImum [283]

Answer:

x = 101°

y = 46°

Step-by-step explanation:

The question tells us that  ΔSTU is similar to ΔSVW. This means that the corresponding angles in each triangle are the same. We can write that like this:

∠UST = ∠WSV

∠SUT = ∠W

∠STU =  ∠V

We can then fill in the angles we know into these statements.

33° = 33°

101° = x

y = 46°

Now we know the values of x and y.

x = 101°

y = 46°

What is the average rate of change for ƒ(x) = −3x + 79 over the interval 2 ≤ x ≤ 4?
Ainat [17]

Answer:

The average rate of change is -3.  

Step-by-step explanation:

Given : Function f(x)=-3x+79 over the interval 2 ≤ x ≤ 4.

To find : What is the average rate of change ?

Solution :

Function f(x)=-3x+79 over [2,4]

The rate of change is the slope of the line,

So, \text{Rate of change}=\frac{f(4)-f(2)}{4-2}

f(4)=-3(4)+79

f(4)=-12+79

f(4)=67

f(2)=-3(2)+79

f(2)=-6+79

f(2)=73

Substitute,

\text{Rate of change}=\frac{67-73}{4-2}

\text{Rate of change}=\frac{-6}{2}

\text{Rate of change}=-3

Therefore, The average rate of change is -3.
