An angle measures 16° less than the measure of a complementary angle. what is the measure of each angle?

Flauer [41]

= 90°/2
= 45°

x = 45° - 16°
x = 29°

y = 45° + 16°
y = 61°

61° and 29° i guess.

Why did I get it wrong ? I’m finding constant B and idk what’s wrong with my step.

Answer:

$\large \boxed{\sf \ \ A=5, \ \ B=-13 \ \ }$

Step-by-step explanation:

Hello,

What you did is correct...

$(Ax-3)(x-2)=5x^2+Bx+6\\\\\text{*** we develop the left side ***}\\\\Ax^2+(-2A-3)x+6=5x^2+Bx+6$

... and you found A by identifying the term in $x^2$ to get A = 5, right?

<u>What about the other terms?</u>

<u />

We can then identify the like terms:

>>> term in $x^2\\$

A = 5

>>> term in x

-2A+3=B

>>> constant term

6 = 6

As we know that A=5 it means that B = -2*5-3=-13

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
