Answer:
w = 9.82
x = 66.73
Step-by-step explanation:
By applying tangent rule in triangle ABD,
tan(81°) =
6.31 =
w =
w = 9.82
Similarly,
tan(39°) =
0.81 =
0.81 =
9.82 + x =
x = 76.56 - 9.82
x = 66.74
Answer:
<h3>He should have found 8 as the exponent, not –8.</h3>Step-by-step explanation:
Given the expression simplified by Pablo as
On simplification we have;
According to one of the law of indices
Applying this law to the question will give;
Based on the calculation above, the exponent of 2 is 8 which means that Pablo should have found 8 as the exponent, not –8.
