Answer:

m<b is 62

AB is 14 mi

BC is 7 miles

m<b is 66

AC is 29.3 miles

BC is 7 miles

Step-by-step explanation:

For the measure part triangles have a measure of 180 degrees 90+28 is 118 180- 118 is 62, for the second part you would just add four since its minus four

for the lengths you look at the congruent sides on the opposing triangles

Find the surface area of the equilateral triangular pyramid.
Alenkinab [10]
We know that
[surface area of the triangular pyramid]=area of the base+3*[area of lateral triangles]
area of the base=12*8/2-----> 48 cm²

area of one lateral triangle=12*10/2-----> 60 cm²
[surface area of the triangular pyramid]=48+3*[60]-----> 228 cm²

the answer is the option 
<span>B) 228 cm2</span>

Show 2 ways 4 people 6-segment chewy fruit worm in each case, how many segments does each person get?
finlep [7]

Question:

Show 2 ways that four people can share a 6-segment chewy fruit worm.

In each case how many segments does each person get ?

Answer:

a. Each\ Person = 1.5\ segments

b. Each\ person = 3\ segments

Step-by-step explanation:

Given

Segments = 6

People = 4

Method 1: Simply divide the number of segments by the number of people.

Each\ Person = \frac{Segments}{People}

Each\ Person = \frac{6}{4}

Each\ Person = 1.5

Method 2:

Start by taking LCM of 4 and 6

4 = 2*2

6 = 2 * 3

LCM = 2 * 2 * 3

LCM = 12

This means that you divide the chewy fruit into 12 segments. This is done by cutting each segment in half.

Each person gets:

Each\ person = \frac{Segments}{People}

Each\ person = \frac{12}{4}

Each\ person = 3

So, when the fruit is further divided to 12, each person gets 3 segments of the division.
