. If a = 120°, find the measure of angles b, c and d.<br> Explain your reasoning.
Alchen [17]
∡b is a vertical angle to ∡a and therefore a twin, and we know that ∡a = 120°, thus since ∡b = ∡a, ∡b = 120° as well.

a full circle has a total of 360°, ∡d and ∡c are vertical angles, namely two angles across from each other at a junction, and therefore ∡d = ∡c.

∡a + ∡b is 120° + 120° thus 240°, since a circle has a total of 360°, 360 - 240 = 120, so the other two angles pick up that slack and divide it among each other evenly, 120/2 = 60, so ∡d = ∡c = 60°.

Need help with this plzzz

Line 1

Natalie was supposed to use PEMDAS (as we all do when doing math), which stands for: Parentheses, Exponents, Mulitplication, Division, Addition, Subtraction. However, Natalie subtracted 1 from 2 before multiplying 6 by 4 and dividing it by 2.

Hope this helps!!

F(x)= {2ˆx, X&lt;0<br><br> {-xˆ2 -4x +1, 0 2
N76 [4]

Answer:   If x is less than 0, 2 to the power of that negative x will be 1/2^x.

So, 1/2^x.

Step-by-step explanation:

I can't go any further without more info about value of x.

Help pls
Alenkasestr [34]

Answer:

Jay could be thinking of 11  

Step-by-step explanation:

Prime numbers are the numbers that have two factors only, 1 and itself as

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, .................

All prime numbers can divide by 1 and itself only

∵ A number is a prime number

∵ The sum of its digits is 1 more a square number

∴ The sum of its digits = 1 + x, where x is a square number

→ We will start with the first prime number of 2-digits

∵ 11 is a prime number

∵ The sum of its digits = 1 + 1 = 2

→ Substitute it in the equation above to find x

∴ 2 = 1 + x

→ Subtract 1 from both sides

∵ 2 - 1 = 1 - 1 + x

∴ 1 = x

∵ 1 is the square of 1

∴ Jay could be thinking of 11  

<em>You can check some of the other prime numbers to find another number</em>

Solve for x and y simultaneously
Alchen [17]

Answer:

x=1 , y= 2

Step-by-step explanation:

solving for x:

2x=3(3-x) - 4

- multiply 3 by everything in the parentheses

2x= 9-3x-4

- add 3x to both sides

5x=9-4

5x=5

- divide each side by 5( isolating x)

x=1

solving for y:

y= 3- (1)

- input our solved value for x in the orginal equation

y=2
