calculate the side lengths a and b to two decimal places angle a is 64 angle b is 85 and line ab is 9.3? PLEASE HELP ASAP

qaws [65]

∠C = 180° - (∠A + ∠B) = 180° - (64° + 85°) = 180° - 149° = 31°
$AC= \frac{9.3*sin(85)}{sin(31)} = \frac{9.3*0.9962}{0.515} =17,99 \\ \\ BC=\frac{9.3*sin(64)}{sin(31)} = \frac{9.3*0.8988}{0.515} =16,2$

Factor 75t2 + 12.<br> 3(5t + 2)2<br> 3(25+2 +4)<br> 3(251-4)

frosja888 [35]

Answer:

$75t^2+12=3(25t^2+4)$

Option C)

Step-by-step explanation:

Here we are given with the expression $75t^2+12$

The GCF of $75t^2$ and 12 is 3

Hence we take 3 as GCF and bring it in front of the bracket.

$3(25t^2+4)$

It can not be factorise furthure as there is no GCF of 25 and also there is no rule for sum of squares so that we may apply it on this. Hence the answer would be

$3(25t^2+4)$

Option C)
