What is the value of x <br><br>x=2.25<br>X= 11.25<br>x= 13<br>x= 22

Gemiola [76]

we know that

The sum of the internal angles of a triangle must be equal to $180$ degrees

see the attached figure with letters to better understand the problem

m∠B+ $(6x+1)=180$ °-----> by supplementary angles

m∠B= $179-6x$

m∠A= $2x+10$

m∠C= $79$

m∠A+m∠B+m∠C= $180$

Substitute

$(2x+10)+(179-6x)+79=180\\ -4x+268=180\\ 4x=268-180\\ 4x=88\\ x=22\ degrees$

therefore

the answer is

the value of x is equal to $22\ degrees$

Answer:

(4+5-2+1)- (7+3-8+6) = 0

Step-by-step explanation:

you look for what numbers when subtracted equal zero (in this case each of the parentheses is 8) in each of the parentheses and combine them at the end to form the final equation.

IF 24 IS ADDED TO A NUMBER, IT WILL BE 3 TIMES AS LARGE AS IT WAS ORIGINALLY. FIND THE NUMBER

Romashka [77]

$x-the\ number\\\\x+24=3x\ \ \ \ \ \ |subtract\ 24\ from\ both\ sides\\\\x=3x-24\ \ \ \ \ \ \ |subtract\ 3x\ from\ both\ sides\\\\-2x=-24\ \ \ \ \ \ \ \ |divide\ both\ sides\ by\ (-2)\\\\\boxed{x=12}\leftarrow answer$

Answer:

$f$ < $132$

Step-by-step explanation:

$Greetings!$

$I'm~Isabelle~Williams~and~I~will~be~answering~your~question!$

$Subtract~16~from~both~sides:$

$\frac{f}{4} +16-16$ < $49-16$

$Simplify:$

$\frac{f}{4}$ < $33$

$Now,~multiply~both~sides~by~4:$

$\frac{4f}{4}$ < $33\times4$

$f$ < $132$

$Hope~my~answer~helps!~Have~a~great~day~ahead!$
