Answer:

-7

Step-by-step explanation:

so you have to do PEMDAS

first parenthesis 6-1 is 5

then multiplication 5x4 is 20

the subtraction 23-20-2(5)

2x5=10

23-20=3

3-10=-7

Answer:

WX = 8 mm

Step-by-step explanation:

To be able to solve for WX, we need to first find the size of angle $\angle z$ .

We use the law of sines in the blue triangle to do such:

$\frac{sin(z)}{11} =\frac{sin(133)}{20} \\sin(z)=\frac{11\,sin(133)}{20} \\sin(z)=0.4022$

Now we can use this value in the larger right angle triangle where WX is the opposite side to angle $\angle z$ , and the 20 mm side is the hypotenuse:

$sin(z)=\frac{opposite}{hypotenuse} \\sin(z)=\frac{WX}{20}\\0.4022=\frac{WX}{20}\\WX=20\,(0.4022)\\WX=8.044\,\,mm$

which rounded to the nearest integer gives

WX = 8 mm

Answer:The Pythagorean theorem deals with the lengths of the sides of a right triangle. The theorem states that: The sum of the squares of the lengths of the legs of a right triangle is equal to the square of the length of the hypotenuse ('c').

25) The area of a trapezium is 330cm2 and the length of one of

kari74 [83]

Answer

steps

area of trapizium is a+b/2 * h.

we have a=14, h=15, area=330 and we need to find b

so, 14+b/2 * 15=330

we divide 15 on both sides so 14+b/2=22

we multiply 2 on both sides so 14+b=44
