Answer:
<em>We </em><em>know </em><em>that </em><em>the </em><em>exterior </em><em>angle </em><em>of </em><em>a </em><em>triangle </em><em>is </em><em>equal </em><em>to </em><em>the </em><em>sum </em><em>of </em><em>two </em><em>opposite</em><em> </em><em>interior </em><em>angle. </em>
Step-by-step explanation:
So
25x + 57 + x = 45x
26x + 57 = 45x
57 = 45x - 26x
19x = 57
Therefore x = 3

<span>1. </span><span>A penny weighs about 0.1 oz.
Now, we need to find the weights of pennies in pounds
=> always remember that in every 1 oz, there is 0.0625 pounds.
Since 0.1 is 1/10 of 1 oz, we need to find the value of it in pounds.
=> 0.0625 pounds / 10
=> 0.0625 pounds.
Therefore, in 0.1 oz of penny is
equivalent to 0.00625 pounds.
In problem like this, before determining the answer, you need to make sure that
both unit of measurements are the same. If not, then try to convert.</span>
Answer:
B
Step-by-step explanation:
Use the formula for radius and circle circumference.
Since we know the diameter, if we divide that by 2, we can get the radius.
Now we can plug that value into the circumference formula to get the circumference.
*Since we're rounding to the nearest inch.
A= (b sin A)/ sinB
a= (15.8 sin29)/ sin36
a= 13.03 cm
