The example of a right angle is that it's exactly 90°, the acute angle is less than 90°, and the obtuse angle is more than 90° but less than 180°.

Rewrite! Write an new and equivalent equation that is easier to solve

RUDIKE [14]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - an equation in it's general form

To do - convert the given equation into a form that is easy to solve

Given equation -

$\bold{(x + 2) {}^{2} + 4(x + 2) - 5 = 0} \\$

solve the parenthesis so as to obtain simpler terms

$\bold{\implies \: ( x {}^{2} + 4x + 4 ) + 4x + 8 - 5 = 0}\\$

solve the like terms and you'll obtain the required equation !

$\bold{\implies \: x {}^{2} + 8x - 7 = 0}$

Please help me will mark brainliest!!! Provide a hand drawn graph attachment pls

Travka [436]

The graph is shown below. I used GeoGebra to create the graph. The graph is restricted on the domain $0 \le x \le 2$ meaning that everything to the left of x = 0 is not drawn, and the same for everything to the right of x = 2.

A table of values is included as well. Each row in the table represents an ordered pair point (x,y) that is on the blue cosine graph.

Answer:

$length = \sqrt{ {(x _{2} - x _{1} ) {}^{2} + (y _{2} - y _{1} )}^{2} } \\ = \sqrt{ {(2 - ( - 7))}^{2} + {( - 5 - 4)}^{2} } \\ = \sqrt{ {9}^{2} + {( - 9)}^{2} } \\ = \sqrt{81 + 81} \\ \sqrt{162} \\ = 12.7 \: units$
