A triangle has angle measurements of 56°, 54°, and 70°. What kind of triangle is it?

alexira [117]

Answer:

Right, I am an idiot so i might be wrong

Step-by-step explanation:

Every triangle has three angles which sum to 180 degrees.

There are three types of triangles based on the measures of its angles.

Right Triangle - Has one 90 degree angle

Acute Triangle - All angles less than 90 degrees

Obtuse Triangle - One angle greater than 90 degrees

In this example we are given 2 angles and must find the measure of the 3rd.

a + 56 + 34 = 180

a + 90 = 180

a = 90

Therefore, it is a Right Triangle.

What is the best approximation for the circumference of a circle with a diameter of 300 ft?

geniusboy [140]

Hello!

$\bf Answer$

The best approximation for the circumference is $\boxed{ \bf 942~ft.}$

______________________________________________________

$\bf Explanation$

c = 2 $\pi$ r

r = 300 ÷ 2

r = 150

c = 2 × 3.14 × 150

c = 942

Viktor [21]

Answer:

[See Below]

Step-by-step explanation:

__________________________

✦ Solve for $(1*10)+(4*1)+(7*0.01)+(2*0.001)$ :

__________________________

✦ Solve Parenthesis first:

$(1*10)=\bold1\bold0$

$(4*1)=\bold4$

$(7*0.01)=\bold0\bold.\bold0\bold7$

$(2*0.001)=\bold0\bold.\bold0\bold0\bold2$

__________________________

✦ Add all the values together:

$10+4+0.07+0.002=\bold1\bold4\bold.\bold0\bold7\bold2$

__________________________

So Mikayla wrote the decimal correctly.
