3 and 2 would be 122 since 3 and the 58° are a linear pair making them add up to 180. And 3 and 2 are vertical so they would be congruent.
4 would then have to be 38 since the three angles would have to measure up to 180.
And the 1 would have to be 36 with the same reasoning as before.

As Angle(2) and Angle(3) are Vertically Opposite Angles, they should be Equal.

Let us Take Angle(2) = Angle(3) = X

The Opposite Angle to 58° will also be 58° as they are Vertically Opposite Angles.

We can Notice that Angle(2), Angle(3) and Both the 58° Angles together make a Complete Angle (i.e. 360°)

⇒ Angle(2) + Angle(3) + 58° + 58° = 360°

⇒ Angle(2) + Angle(3) + 116° = 360°

⇒ Angle(2) + Angle(3) = 360° - 116°

⇒ Angle(2) + Angle(3) = 244°

⇒ X + X = 244°

⇒ 2X = 244°

⇒ X = 122°

We took Angle(2) = Angle(3) = X

⇒ Angle(2) = Angle(3) = 122°

Now let us go for the Upper Triangle :

As Sum of Angles in a Triangle = 180°

Angle (1) + Angle(2) + 22° = 180°

Angle (1) + 122° + 22° = 180°

Angle (1) + 144° = 180°

Angle (1) = 180° - 144°

Angle (1) = 36°

Now let us go for the Lower Triangle :

As Sum of Angles in a Triangle = 180°

Angle (3) + Angle(4) + 20° = 180°

Angle (4) + 122° + 20° = 180°

Angle (4) + 142° = 180°

Angle (4) = 180° - 142°

Angle (4) = 38°

I don’t know how to do this question
lubasha [3.4K]

let x represent the number of apples and y represent the number of oranges.

TOTAL: x + y = 112  

                  y = 112 - x

PEELED: \frac{3}{8}x = \frac{1}{2}y

(8)\frac{3}{8}x = (8)\frac{1}{2}y

3x = 4y

3x = 4(112 - x)

3x = 448 - 4x

7x = 448

x = 64

y = 112 - x

  = 112 - 64

  = 48

a) There are 64 apples and 48 oranges

Peeled apples: \frac{3}{8}x = \frac{3}{8}(64)= 3(8) = 24

Unpeeled apples: 64 - 24 = 40

Unpeeled - Peeled: 40 - 24 - 16

b) there are 16 more unpeeled apples than peeled apples

What is 19a-3(a-6)=78
Ivan

Answer:

a = 3.75

Step-by-step explanation:

First distribute the -3 to (a - 6), which gives you the equation, 19a - 3a + 18 = 78. Then subtract the 3a from 19a, which gives you 16a + 18 = 78. Then subtract 18 from both sides and you get 16a = 60. Divide 60 by 16 and you get 3.75 as your a.
