Elsa's magic wand can cast 53 spells. Her wand can cast 17fewer spells than her sister Anna's wand, which is a little bigger and

Mademuasel [1]

Answer:

Anna's wand can cast 70 spells

Step-by-step explanation:

Elsa's wand can cast 53 spells

her wand casts 17 fewer cells than her sister Anna's

Amount of spells cast by Anna's wand = ?

We write the question down in the form of an equation

$x - 17 = 53$

where $x$ is the amount of spells Anna's wand can cast.

we then proceed to solve by collecting like terms to different sides of the equation. We'll have

$x = 53 + 17$

which leaves us with

$x = 70$

This means that Anna's wand can cast 70 spells.

Pls help I don't understand this

Rudiy27

<h3>Answer:</h3>

By angle bisector property,

11x + 23 = 8x + 35
11x - 8x = 35 - 23
3x = 12
x = 4°

So, m∠ABD = 8x + 35

8 × 4 + 35
32 + 35 = 67°

m∠CBD = 11x + 23

11 × 4 + 23
44 + 23 = 67°

m∠ABC = 67° + 67° = 134°

Answer:

39 degrees.

Step-by-step explanation:

We want an angle x such that 0 < x < 360 and angle x is coterminal with an angle of measure 399 degrees.

so x = 399 - 360 = 39 degrees
