Answer:
A.) 40°
Step-by-step explanation:
A triangle is equal to 180°
Angle X and Y has the same angle, so both have 70°.
So:
70° × 2= 140°
To find the degree of the last angle, subtract the known degree, which is 140°, from the overall degree, which is 180°.
So:
180° - 140°= 40°
Answer= 40°
I hope this helps! :)
X=area of Sahara.
y=area of the Gobi Desert.
We suggest this system equations:
x+y=4000000
x=7y
solve by susbstitution method.
(7y)+y=4,000,000
8y=4,000,000
y=4,000,000 / 8=500,000
x=7y
x=7(500,000)=3,500,000
The area of Sahara=3,500,00 miles².
The area of the Gobi Desert=500,000 miles²
To check:
Te sum of their areas is : 3,500,000 miles²+500,000 miles²=4,000,000 miles²
Te area of sahara (3,500,000 miles²) is 7 times the area of the Gobi Desert (7*500,000 miles²=3,500,000 miles²).
Answer:
2/9
Step-by-step explanation:
The probability of getting any letter once is 1/3
The probability of getting any combinations = 1/3 * 1/3 = 1/9
The probability of getting two of the combinations = 1/9 + 1/9 = 2/9
You plug 3 into B so 2(3) + 9 = 15
