Hello wonderful person!!

Okay, so first of all, welcome to brainy
Second, you have to determine whether they are equal to each other and are the same. For example, if i say 2/4 is equal to 4/8, it's considered proportional.

Hope you understand this, and have a GREAT day!! :)

Pls help it due ASAP and show workings

Effectus [21]

Answer:

it's 70°

Step-by-step explanation:

well first by vertical angles we know that

$\angle BAC = \angle DAE\\\\\angle DAE = 4x+6$ ( I don't know how to put the symbol xd)

and given we know that

$\angle EAF = \angle EAD = 4x+6$

solving for x

we know that

$\angle CAD = 180\\\\\angle CAB + \angle ABD = 180\\\\4x+6+6x+14=180\\\\10x+20=180\\\\10x=160\\\\x=16$

and now for $\angle EAF$

$\angle EAF = 4x+6\\\\\angle EAF = 4(16)+6\\\\\angle EAF = 64+6\\\\\angle EAF = 70$

16 less than maliks height is 43<br> Translate this sentence into an equation

forsale [732]

We can think of the number of Malik’s height as a variable. I’ll use h.

“16 less than Malik’s height”
Less than is a subtraction phrase. So you know that you will be using subtraction in this equation.

Malik’s hight is h. 16 - h.

And we know that it equals 43. Therefore, 16 - h = 43.

Hope this helps
