Which property would allow you to use mental computation to simplify the problem 27 + 15 + 3 + 5? additive identity additive inv
Fofino [41]

Answer:

Commutative Property

Step-by-step explanation:

Additive Identity: If you add a real number to zero or add zero to a real number, then you get the same real number back.

Additive Inverse: When you add the same number but reversed sign, you get 0.

Commutative Property: a + b = b + a

Addition distributive property: a(b+ c) = ab + ac.

In this case, we use the commutative property:

27 + 15 + 3 + 5 = 27 + 3 + 15 + 5.

We know that 27 + 3 = 30 and 15 + 5 = 20, so we get 50 quickly using mental math.

Answer:

<h3>20.6 ft</h3>

Step-by-step explanation:

You must use the trigonometric function.

In this case, it will be tangent.

tangent=\dfrac{opposite}{adjacent}

We have

\theta=38^o,\ opposite=r,\ adjacent=20

\tan38^\approx0.7813

Substitute:

\tan38^o=\dfrac{r}{20}

\dfrac{r}{20}=0.7813              <em>multiply both sides by 20</em>

r=15.626

Tree height is r + 5.

Therefore

r+5=15.626+5=20.626\approx20.6\ ft
