Answer:

B. 45

Step-by-step explanation:

45 - 45 -90 triangle

sinA = sinB

45 = 45

45 + 45

= 90

Answer:

Step-by-step explanation:

∵A＝sinB

∴∠A＝∠B

∵ΔABC is RTΔ

∴∠C＝90°

∴∠A＋∠B＝180°－90°＝90°

∴∠A＝∠B＝45°

The Perimeter is x+38

OLga [1]

P=x+38

add all individual sides together (is also the perimeter):
p=(x+3)+(x-5)+x+(x-2)+(x-4)+(x-1)+(x-1)
=7x-10

set both p equal:
x+38=7x-10
38=6x-10
48=6x
8=x

then insert x=8 in all the side/perimeter equations:
p=x+38=8+38=46

sides:
x=8
x-2=8-2=6
x-1=8-1=7
x-4=8-4=4
x-5=8-5=3
x+3=8+3=11

A shelf holds 3 novels, 2 biographies, and 1 history book. Two students in turns choose a book at random. What is the probabilit

Vinvika [58]

I'll do the first one:
Both novels.

Student 1 picks a novel. There are 3 novels out of 6 books total.

Now there are 5 books left.

Student 2 picks a novel. There are 2 novels out of 5 books since the other student took a novel.

To find the probability you would multiply the probability student 1 gets a novel and the probability student 2 gets a novel.

$\frac{3 Novels}{6 Books} x \frac{2 Novels}{5 Books} = \frac{6}{30} = \frac{1}{5}$

So the probability is 1/5. Or 20%

Which equation is it please help me !!

iren [92.7K]

Answer:

y-8x=-2

Step-by-step explanation:

so the slope of the perpendicular line has to the negative receprical of the slope of this line which gives

-(-8)=8

let us put all the equations into slope intercept form

a.y=-8x+6

b.y=-1/8x-5

c.y=1/8x-5

d. y=8x-2

y=mx+b

as you can see the only line with a slope of 8 is y-8x=-2
