{ \large{ \implies{ \sf{Area \: \: of \: \: Trapezium =  \dfrac{1 \times (b1 + b2) \times h}{2} }}}}

{ \large{ \implies{ \sf{Area =   \dfrac{1 \times{ \cancel {16 } {}^ { \:  \: 8} }\times 19}{ \cancel2} }}}}

{ \large{ \therefore \: { \sf{Area = 1 9\times 8 = { \boxed{ \sf{152} \:  \: m {}^{2} }}} \:  \: Ans.}}}

To find the height of a pole, a surveyor moves 150 feet away from the base of the pole and then, with a transit 4 feet tall, mea
ladessa [460]

Answer: The answer is 139 feet

H = height of the pole =?

BC = ED = height of the transit = 4 ft

CD = BE = distance moved away from the base of the pole = 140 ft

Consider the ΔABE

tan44 = AE/BE

tan44 = h/140

h = 140 tan44

h = 135.2 ft

H = height of pole = AE + ED = h + ED = 135.2 + 4

H = 139.2 ft

What is the answer to:

Weird way to write it but alright! (Sideways) 

19pq^-2 x 5pq^6 = ?

These problems are pretty much single operations between each of the variables / constants. 

So it's like this: 

(19*5)(p*p)(q^-2*q^6) = ?

19*5 is 95.

For p*p remember that when two variables multiply there given powers add. In the case where the powers are not shown (like in the case of p*p) they are always assumed to be 1. So what is 1+1? 2. 

p*p is p^2

For q^-2*q^6 it is the same deal with the previous problem. So now the problem looks like this: 

-2 + 6 = 4 
(The two is negative, because the power is negative 2) 

So, q^4. 

Our final answer is all of the combined.... like a so: 

95p^2q^4
