Using The Triangle Sum Theorem. Determine The Angle Measureof &lt;1.3831(78 And 31 Degrees)

Answers

Answer 1

Answer:

71 degrees

Step-by-step explanation:

Hi there!

The sum of the interior angles of a triangle is always 180 degrees.

Knowing this, to solve for the measure of angle 1, subtract 78 and 31 degrees from 180:

180-78-31

= 71

Therefore, angle 1 measure 71 degrees.

I hope this helps!

Find the x-intercept and y-intercept for the graph of 27x - 18y = 54
A.
x-intercept = 0.5, y-intercept = 0.3

B.
x-intercept = 2, y-intercept = -3

C.
x-intercept = 3, y-intercept = -2

D.
x-intercept = 4, y-intercept = 3

Answers

Your answer would be B.

Explanation:

Notice that when x = 0 the value of y is 3/-1 so this line "cuts" the y axis at y=-3.00000

y-intercept = 6/-2 = 3/-1 = -3.00000


When y = 0 the value of x is 2/1 Our line therefore "cuts" the x axis at x= 2.00000

x-intercept = 6/3 = 2

Find the measures of the indicated angles pictures included!!!

Answers

Answer:

25

Step-by-step explanation:

The angles b and 65 are complementary, meaning they sum to 90 degrees. You know this because those 2 angles and the right angle are sitting on a straight line. So, together they equal 180 and 180-90 is 90. Therefore, angle b+65 must equal 90. So, simply subtract 65 from 90 to get the answer, 25.

What are digits?

In a positional numeral system, a numerical digit is a single sign that can be used singly or in combination to represent numbers.

A digit is a part of a set that, when combined, makes up a numeration system.

For example 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 are digits.

The place value of a general abcd digit is given by

d = ones

c = tens

b = hundreds

a = thousands

So,

In the given number 72,204

4 = ones

0 = tens

2 =  hundreds

2 = thousands

7 = hundred thousand

Hence "In the number 72,204 the ones, tens, thousand, and ten thousand will be 4,0,2, and 7 respectively".

Find the least number which when divided by 28, 50 and 140 leaves a remainder 7 ​

Answers

Answer: 21

Step-by-step explanation:

Let's solve :

First we have to find LCM (lowest common multiple) of the given number, i.e 700.

28 = 2 × 2 × 7

50 = 2 × 5 × 5

140 = 2 × 2 × 5 × 7

LCM = 2 × 2 × 5 × 5 × 7 = 700

now, let's add 7 to 700

We get the required number as 707
