Part a: The value of x is 33°

Part b: The measure of each base angle is 69°

Explanation:

It is given that the vertex angle of an isosceles triangle measures 42°.

The base angle in the triangle has a measure of $(2x+3)^{\circ}$

Part a: To determine the value of x

Since, in an isosceles triangle the base angles are always equal.

Thus, the three angles in an isosceles triangle add up to 180°

Hence, we have,

$42+2x+3+2x+3=180$

$42+4x+6=180$

$4x+48=180$

$4x=132$

$x=33^{\circ}$

Thus, the value of x is 33°

Part b: To find the measure of each base angle.

Base angle = $(2 x+3)^{\circ}$

Substituting $x=33^{\circ}$ , we get,

$Base \ angle = (2(33)+3)^{\circ}$

$=(66+3)^{\circ}$

$=69^{\circ}$

Thus, the measure of each base angle is 69°

The larger of two numbers is eight more than three times the smaller number. The sum of the two numbers is fifty-two. Find the t

Dmitry [639]

So... we have two numbers
say "a" and "b"

one is larger than the other, let us say, "b" is larger than "a"
by how much?
well, "<span>eight more than three times"
three times the smaller is 3 * a, or 3a
eight more than that is 3a + 8

so b = 3a+ 8
the sum of both of them is 52
so, we know that

a + b = 52

run a substitution on "b" on the 2nd equation, and solve for "a"
once you find "a", plug it back in the 2nd equation, to get "b"

Two six sided die are rolled, one after another. In the sample space of all possible results, how many of the sums are not great

Softa [21]

There are only 3 patterns that exceed the sum of 10 which are: 5-6,6-5,6-6.
Which gives us 33 patterns. Which makes 33 sums not greater than 10.
