Answer:

44.1

Step-by-step explanation:

Cosine = Adjacent over Hypotenuse

Adjacent of ∠T = 28 and hypotenuse = 39

Which means that $cos(x)=\frac{28}{39}$

Now we solve for x

To get rid of the "cos" we take the inverse of cos ( which is $cos^-^1$ ) and apply it to each side

$cos^-^1((cos)x) = x\\cos^-^1(\frac{28}{39} )=44.11461855$

We're left with x = 44.11461855

Our last step is to round to the nearest tenth and we get that the answer is 44.1

Find the area of this parallelogram?

Jet001 [13]

So, the area of a parallelogram is the base times the height or

$a = b \times h$

a being area

b being base

h being height

the height is 8 cm and the base is 15 cm

(remember: the heght should be perpendicular to the base)

so we plug in 8 for h and 15 for b to get

$a = 15 \times 8$

and 15 × 8 = (10 × 8) + (5 × 8) = 80 + 40 =120

So the answer is 120

2log(x-3)+1=5<br><br> can someone explain how to solve for x?

Brums [2.3K]

$\bf 2log(x-3)+1=5\iff 2log_{10}(x-3)+1=5\\\\\\ 2log_{10}(x-3)=4
\\\\\\
log_{10}(x-3)=\cfrac{4}{2}\implies log_{10}(x-3)=2\\\\
-----------------------------\\\\
{{ a}}^{log_{{ a}}x}=x\impliedby \textit{using this cancellation rule}\\\\
-----------------------------\\\\
10^{\cfrac{}{}log_{10}(x-3)}=10^2\implies x-3=10^2\implies x=100+3$
