Answer:
Triangle 1: 3.5
Triangle 2: 1.8
Triangle 3: 0.6
Triangle 4: 6.12
Step-by-step explanation:
The area of a triangle is always 1/2 the base times the height.
To find the number of terms in the arithmetic sequence, we need to use the formula
where
is the nth number,
is the first number, n is the number of terms and d is the difference of the two consecutive numbers.
7373 = 1313 + (n - 1)(303)
7373 = 1313 + 303n - 303
7373 = 1010 + 303n
7373 - 1010 = 303n
6363 = 303n
6363 ÷ 303 = n
n = 21
Therefore, there are 21 terms in the arithmetic sequence given.
Answer:
p = 14
Step-by-step explanation:
Side BD is common to both triangles. Moreover, the two triangles are congruent. This means that the side of length 7p is congruent with the side of length p + 84. Thus, 7p = p + 84, or 6p = 84, or p = 14.
