4 0

Answer:

Step-by-step explanation:

In triangle ADC,

b+50+60=180(sum of angles of triangle equals 180)

or,b=180-110

▪b=70

also,

In triangle ABD,

angleA = 30+50=80

now,

a+80+60=180(sum of angles of traingle equals 180)

or,a=180-140

▪a=40'

18 months ……33inches, weight 25.5 pounds

When he was born = 9 months…20 inches, weight 8, 4 pounds

Every 9 months his height growth is 33-20 = 13 inches, his weight is 25.5-8.4=17.1 pounds 

<span>Pounds.  This means, for every 9 months, his growth is 13 inches and his weight is 17.1 pounds. For example we can determine his growth in 3 years.</span>

2 angles measure 40 degrees each, what does the third angle measure? what type of triangle is it?
zimovet [89]

Answer:

Part a): 100 degrees

Part b): Isosceles Triangle

Step-by-step explanation:

Part a): Since the angle measures of all triangles add up to 180 degrees and since the other two angles are 40 degrees, which add up to 80, we can use subtraction to find the answer.

180 - 80 = 100

Part b): Since only two of the three angles in this triangle have the same measure, we can find that it is an isosceles triangle, with base angles measuring 40 degrees, and the vertex angle being 100 degrees.
