Nine more than the product of 22 and Gordons height

OverLord2011 [107]

Answer:

9 + 22h

Explanation:

The question is incomplete as Gordon's height is not given. To solve further, we will represent this height with h

So, we have:

nine more than the $product$ of 22 and $Gordons\ height$

More than, in this case means plus (+)

nine + the $product$ of 22 and $Gordons\ height$

Rewrite nine as 9 and substitute h for Gordons height

9 + the $product$ of 22 and h

product, in this case means multiplication (*)

9 + 22 * h

So, the expression is:

9 + 22h

Please help me with these questions. Ill mark brainliest to whoever answers correctly!!

LUCKY_DIMON [66]

Answer:

see below

Step-by-step explanation:

$3(i)\\\\AD=?\\\\\cos (\angle BDA)=\frac{AD}{BD}\\\\\cos (27)=\frac{AD}{3}\\\\AD=3\cos 27\\\\AD\approx 2.67$

$3(ii)\\\\\sin (\angle BCD) = \frac{BD}{CD}\\\\\sin(41)=\frac{3}{CD}\\\\CD=\frac{3}{\sin 41}\\\\CD\approx 4.57$

I'm sorry but i have to go I'll come back in half an hour and finish answering

Find A if B = 50° and α + β = 100°

goldenfox [79]

Answer:

A=30

Step-by-step explanation:

We know through the Angle Sum Property of A Triangle that

all its angles add up to 180 degrees

Hence, A + (a+b) +B= 180

A+100+50=180

A+150=180

A=30
