Answer:

The value of x is 5

Step-by-step explanation:

Given that m1 =7x and m4 =3x+20

Also given that m1 =m4

We have to find the value of x

Since m1=m4

7x=3x+20

To simplify this, subtract 3x

we get

7x-3x=20

4x=20

Now divide by 4

we get

x=5

Hence the value of x is 5

PLEASE HURRY!!! AB = 20 cm, m∠A = 30° , and $m∠C = 45° . Express the number of centimeters in the length of BC in simplest radic

MrRissso [65]

Using the Sine Rule:-

20 /sin 45 = BC / sin 30

BC = 20 sin 30 / sin45

= 20 * 1/2 / 1 / sqrt2
= 20 * 1/2 * sqrt2
= 10 sqrt2 answer
