<h3>What is Supplementary angle?</h3>

When two angles are said to be supplementary angles if their sum is 180 degrees.

A triangle is shown with its exterior angles.

The interior angles of the triangle are angles 2, 3, 5.

The exterior angle at angle 2 is angle 1.

The exterior angle at angle 3 is angle 4.

The exterior angle at angle 5 is angle 6.

We know that the sum of interior and exterior angle of the triangle is 180 degrees.

∠1 + ∠2 = 180°

∠3 + ∠4 = 180°

∠5 + ∠6 = 180°

Then the correct option is C.

More about the Supplementary angle link is given below.

Find the value of 11 +22+33 + ... + 1100.

ella [17]

Answer:

sum of terms: 55550

Explanation:

$\sf S_n = \dfrac{n}{2} (u_{start}+u_{end}})$

Here the number of terms:

1100 ÷ 11 = 100

Using the Formula:

$\sf \dfrac{100}{2} (11+1100)$

$\sf 55550$

Can someone do this for me please?! Just the answer pls

Lana71 [14]

<h2>For the number 1..</h2>

<h2>angle at center = 2×angle at circumference</h2><h2>the angle at center (o) is equal to 141</h2>

therefore:

<h2>141 = 2x</h2><h2>divide both sides by 2</h2><h2>x = 70.5</h2>

option (A).

( the number 2 and 3 questions aren't correct )

What value of n solves the equation? 2^n=1/8 (the 2^n means with a exponent of n)

inysia [295]

Match bases
if a^x=b^x where x=x then a=b

hmmm
1/8=8^-1=(2^3)^-1=2^-3
so
2^n=2^-3
n=-3
