Complete question :

The sugar maple tree in Joshua's yard is 1/4 the age of the oak tree in his yard. The sugar maple tree is 20 years old. How old is the oak tree?

Answer:

80 years

Step-by-step explanation:

Given that :

Sugar maple tree = 1/4 age of oak tree

Age of sugar maple tree = 20

Age of oak tree = x

20 = 1/4 * x

20 = x / 4

Multiply both sides by 4

20 * 4 = (x / 4) * 4

80 = x

Hence, Age of oak tree = 80 years

From the midpoint of the line segment whose end points are (5, 9) and (-3, 7)

Dmitry [639]

Mid-point= $( \frac{ x_{1}+ x_{2} }{2} ,\frac{ y_{1} y_{2} }{2}$
Mid-point=( $\frac{5+(-3)}{2} , \frac{9+7}{2}$
Mid-point=(1, 8)

39 3.3 5.1 3.3 x find the value in the triangle shown below

prohojiy [21]

Answer:

x = 102

Step-by-step explanation:

Isosceles triangles have equal angles opposite equal sides. There are two 39° angles in this triangle (opposite the 3.3 sides), so the third one is ...

x° = 180° -2(39°)

x° = 102°

<em>Additional comment</em>

The triangle is "overspecified", meaning more measures are provided than are necessary to completely describe the triangle. As is often the case in such situations, the measures provided are sufficiently inconsistent that two different "right" answers are possible, depending on how you work the problem. The first attachment shows the solution above.

The second attachment shows the solution you might get by using the Law of Cosines. Note that x=101 in this case.
