I will give lots of points please help

Mathematics
1 answer:
marin [14]1 year ago
7 0

Step-by-step explanation:

PART 1:

on the graph you can make a triangle at any point and with any angle measures.

i recommend a smaller right triangle to be easiest.

i recommend the points (0,3) A (3,0) B and (0,0) C

∆ABC angle measurements:

m∠CAB=45°

m∠ABC=45°

m∠ACB=90°

PART 2:

(4,3) D (7,0) E and (4,0) F make an identical right triangle moved 4 squares to the right

m∠FDE=45°

m∠DEF=45°

to find the missing value of the angle EFD we will use subtraction and addition

180-(45+45)

180-90

90

therefore, the m∠EFD=90°

PART 3:

both the angle measures and the shapes of the triangles are the same

PART 4:

i used a 1:1 ratio

sorry for the wait :)

Mary ravi and Alan have a total of $62 in their wallets. Mary has $6 more than Ravi. Alan has 2 times what Mary has. How much do
mixas84 [53]

Answer:

Marry = $17

Ravi = $11

Alan = $34

Step-by-step explanation:

Let us assume

Mary be X

Ravi be Y

Alan be Z

So, the equation in total is

X + Y + Z = 62

It is given that

X = Y + 6

Z = 2X

Now we put the Z value in the total equation, so it would be

X + Y + 2X = 62

3X + Y = 62  .................................... (1)

And can we write

X = Y + 6

X - Y = 6 ................................. (2)

Now substitution these two equations,

3X + Y = 62

X - Y = 6

2X = 68

X = $17

So, Z = 2 × 17 = $34

And, Y

$17 + Y + $34 = $62

So, Y = $11

What is the solution of StartRoot x + 2 EndRoot minus 15 = negative 3?
Brilliant_brown [7]

Answer:

x = 142

Step-by-step explanation:

The problem;

\sqrt{x+2} - 15 = -3

Inverse operations;

\sqrt{x+2} -15 = -3\\                +15     +15\\\\\\\\\sqrt{x+2} = 12\\\\

Now undo the square, by squaring both sides;

\sqrt{x+2} = 12\\.^{2} \\\\\\  \\x+2 = 144

Inverse oeprations;

x + 2 = 144

  -2        -2

x = 142

(8+3)n for n=6 help me please I'm not sure how to answer this problem how do I work this problem to get answer?
Andreas93 [3]

Answer:

54 ~ see below for explanation

Step-by-step explanation:

you're going to replace n with the 6 since n= 6

so (8+3)6

then you're going to add 8+3 in the parenthesis because of PEMDAS

(9)6

you're going to multiply 6 by 9 since 9 is in parenthesis (a number in parenthesis means multiply)

then you get 54 so the answer would be 54.
