Answer:
Angle A: 40°
Angle B: 50°
Angle C: 90°
Side A: 14
Side B: 12
Side C: 11.2 or 11 if you round to the nearest whole number.
Step-by-step explanation:
Angle A;
Since we know angles B and C we can use those to help us find angle since all three angles should add up to 180°.
90-50=40
Angle A= 40°
Side C;
Since we know all the angles now and the other two side lengths, we will use those to help us find Side C.
cos 40°= C/14
C/14= cos 40°
C/14= .8
C= .8 x 14
C= 11.2
Hope this helps! Have a great day! :)
The correct answer choice is:
______________________________________________ [C]: "<span>
Multiply each side by −8, subtract 35 from each side" .
_______________________________________________Explanation:_______________________________________________Given: "</span>
(x + 35) = -7 " ;
We can START by multiply each side of the equation by "-8" to completely get rid of the "
" fraction on the "left-hand-side" of the equation:
since: "
* -8 = 1 ; and: "1" , multiplied by any given value, is equal to that given value; so in effect, the "1" becomes eliminated.
"
* -8 =
*
=
=
= 1 .
____________________________________________________So, given: "
(x + 35) = -7 " ; ;
We multiply each side of the equation by "-8" ;
→ -8 * {
(x + 35) } = -7 * {-8) " ;
→ 1 (x + 35) = 56 ;
→ x + 35 = 56 ;
Then, we SUBTRACT "35" (FROM EACH SIDE OF THE EQUATION) ; to isolate "x" on ONE SIDE OF THE EQUATION; and to solve for "x" ;
→ x + 35 − 35 = 56 <span>− 35 ;
</span>→
x = 21 .

So, as explained, the correct answer is:

multiply 2x3xx3x4 and you get 72
so the answer would be :B
Answer:
x = 4
Step-by-step explanation:
We are to solve for;
-x = -4
A number (n) multiplied by x gives -4. What is the number?
n × x = -4
n is definitely equal to -1
So to get the value of x; we divide -4 by -1 to get 4
Therefore x = 4
Answer:
The dimensions of the prism are 1, 2/3, and 5/3.
Multiplying all of these numbers, we see that the final volume of the prism is 10/9 units, which is also equal to 1 1/9, so the first choice (the one to the left) is correct.
Let me know if this helps!
