Answer:

arc HK = 60

Step-by-step explanation:

angle HLK is an inscribed angle and arc HK is the arc it intercepts

an inscribed angle is equal to half the measure of the arc it intercepts

this can also be said as the intercepted arc is equal to twice the measure of the inscribed angle

Hence arc HK = 30 * 2 = 60

2.8y + 6 +0.2 y =5y -14

serious [3.7K]

2.8y + 6 + 0.2y = 5y - 14
(Simplify like terms in first half of equation)
3y + 6 = 5y - 14
(Subtract both sides by 3y)
6 = 2y - 14
(Flip)
2y - 14 = 6
(Add both sides by 14)
2y = 20
(Divide both sides by 2)
y=10

3-2i/1+4i include each step necessary in simplifying

Likurg_2 [28]

Answer:

$\frac{3-2i}{1+4i}=\frac{11}{17}-\frac{10}{17}i$

Step-by-step explanation:

$\frac{3-2i}{1+4i}$ <-- Given

$\frac{3-2i}{1+4i}*\frac{1-4i}{1-4i}$ <-- Multiply by the conjugate of the denominator as a factor of 1

$\frac{(3-2i)(1-4i)}{(1+4i)(1-4i)}$

$\frac{(3)(1)+3(-4i)-2i(1)-2i(4i)}{(1)(1)+1(-4i)+4i(1)+4i(-4i)}$ <-- Use the Distributive Property and FOIL

$\frac{3-12i-2i-8i^2}{1-4i+4i-16i^2}$

$\frac{3-10i-8i^2}{1-16i^2}$

$\frac{3-10i-8(-1)}{1-16(-1)}$ <-- Rewrite $i^2$ as $-1$

$\frac{3-10i+8}{1+16}$

$\frac{11-10i}{17}$

$\frac{11}{17}-\frac{10}{17}i$ <-- Rewrite in $a\pm bi$ form

Can you help i give 50 points

Citrus2011 [14]

Answer:

IF It is a right angle triangle then it's one angle

is of 90 degree

Other angle given is 32degree

And sum of all angle of triangle is 180 degree

Therefore by angle sum property

Missing angle =180 - (90+32)

Missing angle =180 - 113

Missing angle =67

The third angle is 6 7 degree

If you are helped with my answer pls tag me brianliest I really want it

en dos líneas paralelas cortadas por una trasversal el valor de un ángulo es 2×-14 y su suplementario mide 3×-18

ASHA 777 [7]

Responder:

x = 42,4

Explicación paso a paso:

Podemos encontrar el valor de x ya que no se nos dice qué buscar

La suma de dos ángulos suplementarios es 180 grados, por lo tanto;

2x - 14 + 3x - 18 = 180

2x + 3x - 32 = 180

5 veces = 180 + 32

5 veces = 212

x = 212/5

x = 42,4

Por tanto, el valor de x es 42,4
