Answer:
52.5
Step-by-step explanation:
Since this is an isosceles triangle, the base angles are the same
The three angles add to 180
R+ T + S = 180
3x+30 + 3x+30 + 12x-15 = 180
Combine like terms
18x +45 = 180
Subtract 45 from each side
18x+45 - 45 = 180-45
18x =135
Divide each side by 18
18x/18 = 135/18
x = 7.5
We want angle R
R = 3x+30
= 3( 7.5) +30
22.5 +30
52.5
Okay so if the pan is 12 inches wide you can divided 3 inches by that and get 4. Then do the same thing for the length, 18, and you get 6. Multiply 6 by 4 to get the number of brownies Pablo cut.
You can check my answer by drawing a box on a piece of paper, and drawing little boxes inside. Keep in mind that each brownie is 1 unit, or 3 inches.
-4.3s + 0.6t - 2.6 is the answer
<h2><em><u>Option</u></em><em><u> </u></em><em><u>B</u></em><em><u>:</u></em><em><u> </u></em><em><u>(</u></em><em><u>10</u></em><em><u>)</u></em></h2>
Step-by-step explanation:
<em><u>Here</u></em><em><u>,</u></em>
13x - 5 = 11x + 15. <em> </em><em> </em><em> </em><em> </em><em>[</em><em>Since</em><em> </em><em>corresponding</em><em> </em><em>angles</em><em> </em><em>are</em><em> </em><em>similar</em><em> </em><em>in</em><em> </em><em>parallel</em><em> </em><em>lines</em><em>]</em>
=> 13x - 11x = 15 + 5
=> 2x = 20
=> <em><u>x = 10 (Ans)</u></em>
