The best way to find the answer is to solve for x. To start you would add 38 and 39, getting 77, then subtract that from 180 to get the last angle in the triangle, 103. Finally, you would subtract 103 from 180, getting 77, to get x. The only thing you need to do now is to look at all of the answers and figure out which one makes sense for the answer you got. You know it can't be x<77 because it doesn't have the or equal to sign. You know it can't be x>103 because 77 is lower than 103. You know it can't be x<39 because 77 is greater than 39, so the answer has to be x > 38.
Answer:
8
Step-by-step explanation:
A cube is equal on all sides. Therefore the cubes must be 3cm x 3cm x 3cm. Therefore, each cube has an area of 27cm^3. The box that the cube has an area in is 3cm x 6cm x 12 cm which = 216cm^3. If you do 
Answer:
a¹⁰
Step-by-step explanation:
So here we have (a⁵)², meaning we need to multiply the exponents to get a¹⁰
Step-by-step explanation:
<em>Given </em>
<em>circumference </em><em>=</em><em> </em><em>1</em><em>2</em><em> </em><em>inch</em>
<em>π</em><em> </em><em>=</em><em> </em><em>3</em><em>.</em><em>1</em><em>4</em>
<em>radius </em><em>(</em><em>r) </em><em> </em><em>=</em><em> </em><em>?</em>
<em>We </em><em>know </em>
<em>circumference </em><em>=</em><em> </em><em>2</em><em>π</em><em>r </em>
<em>1</em><em>2</em><em> </em><em> </em><em>=</em><em> </em><em>2</em><em>*</em><em> </em><em>3</em><em>.</em><em>1</em><em>4</em><em> </em><em>*</em><em> </em><em>r</em>
<em>r </em><em>=</em><em> </em><em>1</em><em>2</em><em> </em><em>/</em><em> </em><em>6</em><em>.</em><em>2</em><em>8</em>
<em>Therefore </em><em> </em><em>r </em><em>=</em><em> </em><em>1</em><em>.</em><em>9</em><em>1</em><em> </em><em>inch</em>
