Step-by-step explanation:
The given matrix equation is:
To find Matrix X, we need to multiply both sides of the equation by 2 to obtain:
This simplifies to;
By scalar multiplication, we multiply each entry in the matrix A by to 2 to obtain matrix X.
Answer:
X=66°
Step-by-step explanation:
Because it is an isosceles triangle, the 2 missing angles are going to be the same size.
Subtract 48 from the total degree of the triangle which is 180.
180-48= 132
now you di ed that by 2 and you’ll know the missing angle.
132/2= 66
Um b is maybe 9n + 5 = 15n
um c is maybe 3 - 5 to the third power =3 - 125 = -122 + 7 = -115
maybe you have to add the positive 15n to -115 = -100n
um d is maybe 3b + 2c - 10c = 3b + -8c = -5 <span />
Answer:
9.65 meters
Step-by-step explanation:
965 cm * 1 m / 100 cm = 9.65 m
Step-by-step explanation:
Since, cos 200°
= 1/sec 200°⇒ cos 200°
= 1/(-1.0641)
= -0.9397
