Answer:
acute
Step-by-step explanation:
Angles between 0 and less than 90 are acute
A 90 degree angle is right
Greater than 90 and less than 180 is obtuse
180 degree angles are straight
45 degrees is less than 90 so it is acute
Answer:
x = 16
Step-by-step explanation:
Δ ABC and Δ ADE are similar , thus the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
11x = 8(x + 6)
11x = 8x + 48 ( subtract 8x from both sides )
3x = 48 ( divide both sides by 3 )
x = 16
Answer:
7x - 10 -y
the y has a + sign as it is on the left hand side of the equation rewriting the equation in standard form makes the y move to the right hand side and then has a negative sign so the equation is written as 7x - 10 - y

Step-by-step explanation:
Answer:
x=-2.5
Step-by-step explanation:
4x+(7-3)5=10
4x+(4)5=10
4x+20=10
subtract 20 from each side
4x=-10
divide each side by 4
x=-2.5
