Step-by-step explanation:

180° = m<A + m<B + m<C

180° = 45° +60° + m<C

180° = 105° + m<C

m<C = 180° - 105 °

What is BC ?<br><br><br> Enter your answer in the box.

tangare [24]

Lines AB and AC are equal so you set up an equation like so...
4x + 1 = 2x + 23
Subtract 1 from both sides.
4x = 2x + 22
Subtract 2x from both sides.
2x = 22
Divide.
x = 11
Now you need to plug in 11 into 3x - 8.
3(11) - 8
= 33 - 8
= 25
So BC is 25.
I hope this helps love! :)

Find the value of x in each of the given figures.

Kaylis [27]

Answer:

Step-by-step explanation:

1) Given figure is a parallelogram

Area = 144 cm²

base * altitude = 144

16 * x = 144

x =144/16

x = 9 cm

2)2) Trapezium

Area = $\frac{a+b}{2}*h$ ; {a and b are parallel sides of trapezium}

( 37 +27 /2) * x = 480 cm²

64/2 * h = 480

32 * h = 480

h = 480/32

h = 15 cm
