What is m∠ABC? Justify your reasoning. Using the addition property of equality, 40 + 15 = 55, so m∠ABC = 55°. Using the subtract

N76 [4]

Answer:

Using the Angle Addition Postulate, 15 + 40 = m∠ABC. So, m∠ABC = 55° after simplifying.

Step-by-step explanation:

The Angle Addition Postulate is gotten from angles placed side by side to form a resulting angle that is the sum of all the individual angles.

If D is the interior of ABC then, ABC is split into two parts i.e ABD and DBC, then the measure of ABC is the sum of the individual two parts

m∠ABC = m∠ABD + m∠DBC.

Using the Angle Addition Postulate:

m∠ABC = m∠ABD + m∠DBC

m∠ABC = 15 + 40 = 55°

m∠ABC = 55°

Answer:

Yes, y varies directly with x, and the equation is $y=1.6x$ .

Step-by-step explanation:

To check where there is a direct relationship between x and y, we need to check whether all the x,y pairs we have fit some rule:

$y=k\times x$ .

For the first pair (x=4, y=6.4),

$6.4=k\times 4$

Therefore $k = 1.6$ .

For the second pair (x=7, y=11.2),

$11.2=k\times 7$

Therefore $k = 1.6$ .

For the third pair (x=10, y=16),

$16=k\times 10$

Therefore $k = 1.6$ .

For the second pair (x=13, y=20.8),

$20.8=k\times 13$

Therefore $k = 1.6$ .

So x does directly vary with y, and we have found out that $k=1.6$ .
