All triangles have a measurement of 180 degrees. Therefore, we can use this information to make an equation to find the value of angle B.
Angle B = 180 - (28 + 36)
Angle B = 180 - 64
Angle B = 116
So, angle B is equal to 116 degrees.
Step-by-step explanation:
This is the answer.... Working shown
Answer:
for first parallelogram
Area of parallelogram = b*h= 3.5*2= 7square unit
for second parallelogram
Area of parallelogram = b*h = 1.8 square unit
or, 3*h = 1.8
h= o.6unit
For third parallelogram
Area of parallelogram = b*h = 20.4square unit
4*b= 20.4
b=5.1 unit
Step-by-step explanation:
One thing for sure it is not b,d,c its a
Answer:
a. L.B. = 20.5
b. U.B. = 21.5
Step-by-step explanation:
Length is measured 21 cm correct to 2 significant figures
a. Lower bound of 21
= 20.5 < 21
= 20.5
b. Upper bound of 21
= 21 < 21.5
= 21.5
