Answer:
60°
Step-by-step explanation:
Complementary angles sum 90°
a + b = 90° Eq. 1
b = a/2 Eq. 2
Replacing Eq. 2 in the Eq. 1
a + a/2 = 90
2a/2 + a/2 = 90
3a/2 = 90
a = 90*2/3
a = 60
from the Eq. 2
b = 60/2
b = 30
Check:
from the Eq. 1
60 + 30 = 90
Answer:
60>30
Then
The larger angle is:
60°
Create three different expressions that are each equal to 20. Each expression should include only these three numbers:
4
-2
10
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The three expressions that use only 4, -2, and 10 and that are equal to 20 are:
4 x 2 - (-2) + 10
4 x 10 + (-2) x 10
-2 x (-2) + 4x4
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
We have,
20
The three expressions that are equal to 20 using only 4, -2, and 10 are:
First expression:
4 x 2 - (-2) + 10
= 8 - (-2) + 10
= 8 + 2 + 10
= 20
Second expression:
4 x 10 + (-2) x 10
= 40 - 20
= 20
Third expression:
-2 x (-2) + 4x4
= 4 + 16
= 20
Thus,
The three expressions that use only 4, -2, and 10 and that are equal to 20 are:
4 x 2 - (-2) + 10
4 x 10 + (-2) x 10
-2 x (-2) + 4x4

-5n+4n-7=8
What is the answer for n and how do you solve it
Answer:
-15
Step-by-step explanation:
First combine like terms, aka the variables
-5n+4n-7=8
-1n-7=8
Then, isolate the variable by adding 7 to both sides
-1n-7+7=8+7
-1n=15
Finally, solve by dividing both sides by -1
-1n/-1=15/-1
n=-15
Answer:
n = -15
Step-by-step explanation:
I'll try my best to explain how I solved this
Equation:
-5n + 4n -7=8
Add the light terms on each side:
-n -7 =8
Separate the variables from the numbers:
-n = 15
Do the operation necessary to solve it:
n = -15

Answer:
134 degrees
Step-by-step explanation:
the angles in a triangle always add up to 180.
86+48=134
to find the last angle you subtract 180-134
this gives you 46 degrees
a straight line is always measured as 180 degrees.
180-46=134
so x=134 degrees
