The sum of all angles of a triangle is equal to 180°

On a isosceles triangle, the base angles are the same.

We add them together 56° + 56° = 112°

To know X, we subtract 112° from the total

180° - 112° = 68°

X = 68°

OR as an equation

56 + 56 + x = 180

112 + x = 180

x = 180 - 112

x = 68

Answer:

The answer is D, 68

Step-by-step

this is the Angles Outside a Circle Theorem

(If a tangent and a secant, two tangents, or two secants intersects in the the exterior of a circle, then the measure of the angle formed is one half the difference of the measures of the intercepted arcs.

one circle = 360 degrees

you do not know the other part of the circle

so... 360 - 248 = 112

now you want to divide 112 by two = 68

x = 68 degrees

Your friend says that the absolute value equation | 3x+8 |-9=-5 has no solution because the constant

sineoko [7]

Answer:

Incorrect

Step-by-step explanation:

We are given the equation:

$\displaystyle \large{|3x+8|-9=-5}$

Add both sides by 9.

$\displaystyle \large{|3x+8|-9 + 9=-5 + 9} \\ \displaystyle \large{|3x+8|=4}$

When we want to tell if the absolute equation has solutions or not, we have to simplify in this form first: or isolate the absolute sign.

$\displaystyle \large{ |ax + b| = c}$

If c ≥ 0, the equation has solutions.

If c < 0, the equation does not have solutions.

Therefore, it does not always matter if the constant on right side is in negative because if there is a number on the left side then there is a chance that the equation has solutions.

From |3x+8| = 4 is equivalent |3x+8|-9=-5 and the right side is 4 which is positive.

Hence, the equation does have a solution!

Help me with this question

kaheart [24]

First combine like terms and put the expression in standard form. This expression is now in simplest form and cannot be simplified anymore.
3a + 10ab - 7a^2b - 10ab^2 + 12ab - (-4) + (-a^2b) - 5a
-10ab^2 - 8a^2b -2a + 24ab - (-4)

Hope this helps
