Answer:
4 m.
Step-by-step explanation:
Length of ladder, L = 4.50 m
Base of ladder from the wall, B = x
Height of the wall, H = 2x
Using Pythagoras theorem




Height of the wall is equal to 2 x 2 = 4 m.
the answer a is 6 and b is 2
Answer:
b = 8
c = 16
Step-by-step explanation:
From the given right triangle,
a =
, m(∠B) = 30°
By applying sine rule in the given triangle,
cos(B) = 
cos(B) = 
cos(30°) = 

c = 16
Further we apply tangent rule,
tan(B) = 
tan(30°) = 

b = 8
Answer:
<u><em>Answer is below</em></u>
Step-by-step explanation:
<em><u>-2 ×^2 - 4y +6</u></em>
<em><u>Evaluate simply means to form an idea of something</u></em>
<em><u>So Evaluate for x=−3,y=−2</u></em>
<em><u>−2(−3)2−(4)(−2)+6</u></em>
<em><u>−2(−3)2−(4)(−2)+6</u></em>
<em><u>Answer =−4</u></em>
