Answer:

<h2>The value of <em>x </em>is 71°.</h2>

Step-by-step explanation:

The given triangle has to equal sides, this means that the triangle isosceles, from which we can deduct from the theorem of isosceles triangles that<em> the angles formed by these two equal sides are congruent.</em>

Also, we know that the sum of all internal angles of a triangle must be 180°. So

$x\° + x\° + 38\° =180\°\\2x\°=180\°-38\°\\x\°=\frac{142\°}{2}\\x\°=71\°$

Therefore, the value of <em>x </em>is 71°.

Find four consecutive even integers whose sum is 84. Find the integers.

mina [271]

Suppose the integers are n , n+2 , n+4 and n+6.
84=n+(n+2)+(n+4)+(n+6)=4n+12.
Subtract 12 from both ends to get.
72=4n.
Divide both ends by 4 to get.
n=18.
So the integers are: 18 , 20 , 22 , 24.

-7^-2<br>does anyone know ?

Leno4ka [110]

Negative exponents mean that you flip the number upside down

so -7^-2 would become 1/-7^2

-7^2 would be 49

so the answer is <em>1/49</em>

(08.04 MC) Christina bought a yoyo from a company that claims that, with each retraction, the string rolls up by 70% of the orig

egoroff_w [7]

Here is the answer to the given problem. So, what Christina wants to find out is the sum of the length after 10 throws given that in each throw, it retracts 70% of the original length. So to continue the given data, here are the results:
4: 1.029
5: 0.7203
6: 0.50421
7: 0.352947
8: 0.2470629
9: 0.17294403
10: 0.12106082
Since she wants to find the sum of the length after 10 throws, we are just going to add the lengths above. So the answer would be this: 9.71752475. To round this off to the nearest hundredth, the answer would be 9.72. Hope this helps.
