Step-by-step explanation:
Vì tam giác ABC vuông tại C nên ta áp dụng định lí pitago=> AB²=AC²+BC²=0.9²+1.5²=3.06=>AB= (3 căn bậc hai của 34)/10
sin B=AC/AB=(3 căn bậc hai của 34)/34
cos B=BC/AB
tan B= AC/BC
cot B= BC/AC
Tương tự suy ra tỉ số lượng giác góc A

Answer:
y = -51
Step-by-step explanation:
y - (-10) = -41
Subtracting a negative number: - (-10) is the same as just adding a positive number + 10, so we'll use this to simplify the expression.
y + 10 = -41
Now, we can subtract 10 from both sides of the equation in order to isolate y.
10 - 10 = 0
-41 - 10 = -51
This means the equation is now:
y = -51
Let's check this answer:
Input -51 as y:
-51 - (-10) = -41
-41 = -41
It works!
This means y = -51 is the answer!
Step-by-step explanation:
Number of sides of the given polygon, n =5
Sum of interior angles =( n-2)180°
=( 5 - 2)180°
= 3*180°
= 540°
Missing angle, x = 540°- (100°+105°+110°+145°)
= 540°- 460°
= 80°
