we know that
The sum of the internal angles of a triangle must be equal to
degrees
see the attached figure with letters to better understand the problem
m∠B+
°-----> by supplementary angles
m∠B=
m∠A=
m∠C=
m∠A+m∠B+m∠C=
Substitute

therefore
the answer is
the value of x is equal to 
Answer:
4080 ft
Step-by-step explanation:
34 yards of ribbon are used to prepare 8 teddy bears. The yards of ribbon used to prepare 320 teddy bears are:
320 teddy bear × (34 yard/8 teddy bear) = 1360 yard
1 yard is equal to 3 feet. The feet corresponding to 1360 yards is:
1360 yard × (3 feet/1 yard) = 4080 feet
1.7 = 1 7/10 = 17/10
3 2/10 = 32/10
32/10 - 17/10 = 15/10 = 1 5/10 = 1.5 feet above ground
Answer:
1. 100cm
2. 300.1cm
3. 200cm
4. 400cm
5. 299.00cm
Step-by-step explanation:
300-200=100
300+0.01=301
300-100=200
300+100=400
300-0.01=299.99
